Frequently Asked Questions

Q1. What kind of file is the Heat Exchanger Data Sheet?

Portable Document Format (PDF):
The PDF format is modeled after the PostScript language and is both device and resolution independent. Data Sheets and publications in the PDF format can be viewed, navigated and printed from a workstation using the freely available Acrobat Reader software from Adobe Systems Inc. Versions of Acrobat Reader run on Windows 95, Windows NT, Windows 3.1, Macintosh, LINUX, IBM AIX, Sun SPARC SunOS, Sun SPARC Solaris, SGI IRIX, HP-UX, Digital Unix and OS/2 Warp.

Printer Control Language (PCL):
PCL is the printer control language for Hewlett Packard and compatible laser printers. data sheet's and publications in PCL4 format are made up of raster graphic images at 300 dpi compatible with an HP LaserJet Series II, which is supported by most laser printers. Due to their size, PCL formatted files are provided as compressed PKzipped self-extracting executable files. These files must be decompressed before use by executing the file in Windows or DOS. Tax forms and publications in the PCL4 format can be viewed, navigated and printed from Windows using the freely available TaxView software from Page Technology Marketing Inc. or can be copied directly to an HP LaserJet Series II compatible printer by following the instructions displayed when decompressing (executing) the file.

PostScript Language Format (PS):
PostScript is a programming language that describes a page to an output device. A page description generally includes the position, scale, and orientation of text, graphic figures, and digitized images. Applications use a driver program to generate the PostScript output file from either an interactive screen display of a graphic image or a batch composition and pagination program. A PostScript interpreter residing within the output device (laser printer, typesetter, or workstation) reads the PostScript file, constructs the page and outputs it based on the abilities of the device. Two versions of PostScript are provided. An 8.5 x 11 letter size containing embedded fonts and the original 11 x 17 ledger size source file that requires some commercially available Adobe type 1 fonts. Due to their size, PostScript formatted files are provided as compressed PKzipped self-extracting executable files. These files must be decompressed before use by executing the file in Windows or DOS.



Q2. When printing some instructions and publications in PDF format all the words run together with no spaces between them, however, everything looks fine on the screen. Is there an error in your documents, or is it my system?

This issue can nearly always be resolved by obtaining and installing the most recent print driver available for your particular make and model printer. Most printer manufacturers, including Hewlett Packard, provide free printer driver updates from their web sites.



Q4. When downloading a PDF form, my web browser window goes blank and I never receive the file.

Should you experience PDF files appearing as a blank window within your web browser after downloading, follow the appropriate steps below to resolve the issue:

Adobe Acrobat Reader
If you are using Adobe Acrobat Reader version 3.0 or earlier, upgrade to version 4.0 or later.

Internet Explorer
Please see Article ID: Q177321 in the Microsoft Support Online database for a possible resolution.

Use the "Save Target As..." or "Save Link As..." option to download the PDF file directly to your hard drive and bypass the Acrobat Reader plug-in.

* Select "PDF File Format" if necessary.
* Select the file(s) you wish to download.
* Click the "Review Selected Files" button.
* When presented with the Results page use the "Save Target As.." option to download the file. This can normally be accomplished by right clicking (left click, if your mouse is configured for left handed operation) on the title link then selecting "Save Target As.." when presented with a menu.
* Use Adobe Acrobat Reader to open the file after downloading.



Q5. How can I download a PDF file directly to my hard drive and bypass the Acrobat Reader plug-in that normally displays the form in my web browser window?

Below is the procedure to use for Internet Explorer with Windows 95 or NT 4.0. If you are using Netscape, substitute "Save Target As..." with "Save Link As...".

* Select "PDF File Format" if necessary.
* Select the file(s) you wish to download.
* Click the "Review Selected Files" button.
* When presented with the Results page use the "Save Target As.." option to download the file. This can normally be accomplished by right clicking (left click, if your mouse is configured for left handed operation) on the title link then selecting "Save Target As.." when presented with a menu.
* Use Adobe Acrobat Reader to open the file after downloading.



Q6. Do you have any other general troubleshooting advice for resolving print problems?

* Raster vs. Vector Modes - You may get more consistent results if your printer driver is set to use Raster mode for graphics. Note, not all printer drivers have this mode.
* Dithering - Set your printer driver’s Graphics/Dithering option to Fine or Coarse for best results when printing half-tone images. A setting of None will produce poor results.
* 600dpi - If you experience problems printing to HP LaserJet printers in the 600dpi mode, try switching back to 300dpi mode or if it is equipped with a PostScript option, use the PostScript mode for 600dpi printing.
* Printer Memory Issues using PDF format - If you encounter problems, such as a "Vmerror" printing to a PostScript Level 1 or 2 printer, it may be because the printer has insufficient memory available. Below are two potential solutions to this problem:
* In the Acrobat Reader General Preferences dialog (select from the File>Preferences menu) you may choose to use Serif only or Sans only for font substitution. This frees up additional memory in the printer and chances are good your document will print successfully.
* Upgrade the printer’s memory.

This document provides troubleshooting suggestions from Adobe Technical Support that may help you resolve non-specific printing problems in Adobe Acrobat 3.0x and 4.0 viewers for Windows. You may find a solution to your printing problem in a more specific document by searching the Technical Solutions database on Adobe's Web site at www.adobe.com.

Before you begin troubleshooting, be sure to check the Acrobat ReadMe file, which may include information or troubleshooting suggestions for your printer.

Determining the Cause of the Problem
Before you can troubleshoot the problem, you need to determine its cause. To determine the cause of the printing problem, complete the following:
1. Print another PDF file:
- If that file prints correctly, the PDF file that doesn't print correctly may be damaged, and you should continue troubleshooting using the solutions in the Resolving Problems Printing a Specific PDF File from an Acrobat Viewer section, below.
- If the file doesn't print correctly, proceed to step 2.
2. Print another type of file (e.g., a *.txt file) from another application (e.g., Microsoft Word or WordPad):
- If that file prints correctly, you know the problem isn't system-wide -- it's only with the Acrobat viewer. See the Resolving Problems Printing Any PDF Files from an Acrobat Viewer section, below.
- If the file doesn't print correctly, the problem is system-wide, and is not specific to Acrobat or your PDF files. The problem could be low system resources, insufficient memory on your printer, or a poor connection between your computer and the printer. Proceed to step 3 to eliminate some likely causes of the problem. If steps 3-6 don't solve the problem, see Resolving Problems Printing Any File from Any Application, below.
3. Restart your computer and then print a PDF file:
- If the file prints correctly, your system may have been out of memory or resources.
- If the file doesn't print correctly, proceed to step 4.
4. Turn off your printer for at least 15 seconds to flush its memory, and then turn it back on and print a PDF file:
- If the file prints correctly, your printer's memory was too full.
- If the file doesn't print correctly, proceed to step 5.
5. Print from another computer:
- If the file prints correctly, the computer you first tried to print from may be unable to connect to the printer or the network correctly. Contact your network administrator or consult your network documentation.
- If the file doesn't print correctly, proceed to step 6.
6. Print a PDF file to another printer:
- If the file prints correctly, the computer you first tried to print from may be unable to connect to the original printer because of a communication, hardware, or memory problem. Make sure that the printer is turned on and connected properly, and then run a self-test on it to make sure that it's working correctly. For instructions, see the printer's documentation. You may want to contact your network administrator for assistance.
- If the file doesn't print correctly, see Resolving Problems Printing Any File from Any Application, below.



Resolving Problems Printing a Specific PDF File from an Acrobat Viewer

If you're having problems printing an individual PDF file, do one or more of the following:

Solution 1
If you're printing from an Acrobat 4.0 viewer, select Print As Image in the Print dialog box. Note that files will print more slowly with Print As Image selected. For more information on Print As Image, refer to page 60 of the online Acrobat 4.0 User Guide.

Note: Although using Print As Image may enable you to print, it does not help you determine the original printing problem. Therefore, it is strongly recommended that you proceed through this troubleshooting guide to try to determine the cause of the problem.

Solution 2
If you're printing to a PostScript printer from Windows 95 or Windows 98, enable the PostScript error handler for the printer (if the printer driver includes this option):
1. Choose Start > Settings > Printers.
2. Right-click your printer and choose Properties from the pop-up menu.
3. Click the PostScript tab.
4. Select Print Postscript Error Information and then click OK.

The PostScript error handler will print a list of any PostScript errors that occur when you print. For help interpreting and resolving PostScript errors, see document 310390, "Troubleshooting PostScript Errors."

Solution 3
Make sure that at least 50% of the system resources are free when printing from an Acrobat viewer. If the system resources are below 50%, exit from all applications but the Acrobat viewer. You may need to restart Windows for it to reflect freed system resources.

To check the amount of available resources:
- In Windows 95 or Windows 98, right-click My Computer, choose Properties from the pop-up menu, and then click the Performance tab.
- In Windows NT 4.0, press Ctrl+Alt+Del and then click Task Manager.
- In Windows 3.1x, choose Help > About Program Manager.

Solution 4
Re-create the PDF file using Acrobat Distiller or the updated Acrobat PDFWriter included with Acrobat 3.0x or 4.0.



Resolving Problems Printing Any PDF Files to a PostScript Printer from an Acrobat Viewer

If you're having problems printing any PDF files from your Acrobat viewer to a PostScript printer, do one or more of the following:

Solution 1
Make sure that you're using the latest version of the Acrobat viewer. You can check Adobe's Web site at www.adobe.com for current version information and updates.

Solution 2
Make sure that you're using the most current printer driver for your printer:
- When printing from Windows 95 or Windows 98, you should use either the Microsoft PostScript printer driver 4.0 or later or the Adobe PostScript printer driver (AdobePS) 4.1 or later. AdobePS 4.x is in the Drivers folder on the Acrobat 3.0x CD. AdobePS 4.2 for Windows 95 and Windows 98 is in the Utilities\Drivers\Win95&98 folder on the Acrobat 4.0 CD. To check the version of most printer drivers in Windows 95 or Windows 98:
1. Choose Start > Settings > Printers.
2. Right-click the printer and then choose Properties from the pop-up menu.
3. Click the Paper tab and then click About.

- When printing from Windows NT, you should use the Microsoft PostScript printer driver included with Windows NT and should also use the most recent Service Pack update, or you should use the Adobe PostScript printer driver (Adobe PS) for Windows NT. AdobePS 5.1 for Windows NT 4.0 is in the Utilities\Drivers\NT folder on the Acrobat 4.0 CD and is also available from Adobe's Web site. To check the version of most printer drivers in Windows NT 4.0:
1. Choose Start > Settings > Printers.
2. Right-click your printer, then choose Properties from the pop-up menu.
3. Click the Device Settings tab, select the device name at the top of the list, then click About.

- When printing to a PostScript printer in Windows 3.1x, you should use either the Microsoft PostScript printer driver 3.58 or later or AdobePS 3.0.1. AdobePS 3.0.1 is in the Drivers folder on the Acrobat 3.0x CD. To check the version of most printer drivers in Windows 3.1x:
1. Open the Printers Control Panel.
2. Select your printer and then click Setup.
3. Click About.

Solution 3
Change the printer driver settings:

In Windows 95, Windows 98, or Windows NT 4.0:
1. Choose Start > Settings > Printers.
2. Right-click your printer, then choose Properties from the pop-up menu.
3. Click the PostScript tab.
4. Select PostScript (Optimize for Portability) and then click OK.

In Windows 3.1x:
1. Open the Printers Control Panel.
2. Select your printer and then click Connect.
3. Deselect Fast Printing Direct to Port and then click OK. If changing this option does not resolve the printing problem, reselect it.

Solution 4
If you're using Windows 3.1x, disable Print Manager:
1. Open the Printers Control Panel.
2. Deselect Use Print Manager and then click OK.

Note: When Print Manager is enabled, all print jobs spool to its print queue in the background. When Print Manager is disabled, print jobs are sent directly to the printer.

Solution 5
Make sure that plenty of free hard disk space is available. All Windows applications create temporary files when printing, which are stored on the computer's free hard disk space. Adobe recommends that free hard disk space be equivalent to at least three to five times the size of the file you're printing. Also, Windows 95, Windows 98, and Windows NT require additional disk space to manage virtual memory. Adobe recommends that at least 25 MB of disk space is free for virtual memory management.

Solution 6
Edit the "Set Temp=" line in the Autoexec.bat file to specify a folder on a non-compressed hard disk that has sufficient free space:
1. Make a backup copy of the Autoexec.bat file .
2. Open the original Autoexec.bat file, which is in the root folder (e.g., C:\), in a text-editing application that can save in text-only format (e.g., Windows Write or Notepad).
3. Locate the line that begins:

Set temp=

The folder designated on the right of the equal sign is the folder where Windows puts most of its temporary files.

4. Note the disk letter and folder name (e.g., C:\Temp). If this line does not exist, you will create it in step 7 after you verify that the folder exists on a hard disk with enough space.
5. In Windows Explorer, verify that the disk and folder exist. If the disk does not exist, choose another disk. If the folder does not exist, create it by clicking on the disk, choosing File > New > Folder, and then typing in the name.
6. Make sure that the disk has at least 10 MB of free space by right-clicking it and choosing Properties from the pop-up menu to see the Free Space field. If the disk does not have enough space, either remove unnecessary files or edit the line in the Autoexec.bat file to use a disk that has enough space.
7. Check the Autoexec.bat file for the following line. If this line does not exist, add it using the format below:

Set temp=C:\Temp

Where "C" is the disk with enough space and "Temp" is the folder you verified or created.

8. Save the Autoexec.bat file in text-only format.
9. Restart Windows.

Solution 7
If you're printing to a network printer, connect your computer directly to the printer and try printing again:
- If files print correctly, your computer can't connect to the printer across the network. Contact your network administrator for assistance.
- If you can't connect directly to the printer, save the PDF file as a PostScript file, copy the PostScript file onto a computer that's connected directly to the printer, and then copy the PostScript file to the printer from a DOS prompt.



Resolving Problems Printing Any PDF Files to a Non-PostScript Printer from an Acrobat Viewer

If you're having problems printing any PDF files from your Acrobat viewer to a non-PostScript (i.e., PCL) printer, do one or more of the following:

Disclaimer: Many of these solutions require you to change your printer driver's properties. The locations for specific properties vary by printer and by printer driver. Therefore, Adobe Technical Support cannot provide detailed information about the location for each property. Contact your printer's manufacturer or refer to your printer's documentation for more information about your printer's options and capabilities.

Solution 1
Make sure that you're using the latest version of the Acrobat viewer. You can check Adobe's Web site at www.adobe.com for current version information and updates.

Solution 2
Make sure that you're using the most current printer driver for your printer. Contact your printer manufacturer for information about which printer driver you should use or for driver updates.

Solution 3
If you're using Windows 3.1x, disable Print Manager:
1. Open the Printers Control Panel.
2. Deselect Use Print Manager and then click OK.

Note: When Print Manager is enabled, all print jobs spool to its print queue in the background. When Print Manager is disabled, print jobs are sent directly to the printer.

Where "C" is the disk with enough space and "Temp" is the folder you verified or created.

8. Save the Autoexec.bat file in text-only format.
9. Restart Windows.

Solution 6
Use the Standard VGA video driver to determine if your video driver is causing the problem. See document 312726 for instructions on specifying the standard VGA driver in Windows 95 or Windows 98. See document 310592 for instructions on specifying the standard VGA driver in Windows 3.1x. To use the Standard VGA video driver in Windows NT, start Windows in VGA mode.

If the error does not occur when you use the standard VGA video driver, contact your video card manufacturer for an updated video driver. If you're already using the current version, try using a different video resolution (e.g., 800x600 rather than 1024x768).

Solution 7
If you're printing to a Hewlett-Packard (HP) LaserJet 4 or 5, print the PDF file in raster mode instead of vector (HP/GL2) mode.

Solution 8
Set up the printer to either download True Type fonts as bitmap fonts or print them as graphics.

Solution 9
Set up the printer driver's Dithering option to get better results printing graphics.

Solution 10
If you're printing at a high resolution (e.g., 600 dpi), reduce the resolution (e.g., 300 dpi).

Solution 11
If your printer has a PostScript option, use the PostScript mode.

Solution 12
If you're using a printer driver included with Windows 3.1x, install a PCL printer driver based on the Universal Printer Driver 3.1.2. For information on obtaining a printer driver based on the Universal Printer Driver 3.1.2, contact your printer's manufacturer.

Solution 13
Ensure the printer has enough memory to print all page elements. To print at 300 dpi, the printer should have at least 2 MB of available random-access memory (RAM). To print at 600 dpi, the printer should have 4 to 6 MB of RAM. For instructions on determining available printer memory, refer to your printer's documentation.

Solution 14
If you're printing to a Hewlett-Packard (HP) LaserJet 4 or 5 that includes the Page Protection mode, enable the Page Protection mode. This mode breaks pages into smaller imageable pieces, processes the data from each piece, stores the processed data in a reserved block of memory and, once each section has been processed, sends the job to the print engine. With Page Protection off, the printer must process the entire page in one large chunk, then send the information to the print engine.

Solution 15
Set up the printer driver to use the Normal print quality option, instead of the Best print quality option.



Problems Printing from All Applications

If you're having problems printing any file from your computer, the problem isn't just with Acrobat, so you'll need to contact Microsoft Technical Support or your printer manufacturer. Always make sure that the printer is turned on, and check the physical connections between the printer and the computer -- the solution may be as simple as reconnecting a loose cable.

Also, note any recent changes to the computer system that may affect printing. Any of the following can cause problems:
- updating hardware or software
- adding new hardware or software
- deleting software
- installing or removing fonts
- connecting to a network
- rearranging or cleaning up files on the hard drive

Keeping a record of changes made to the system can help you troubleshoot printing and other problems.
