• Clear out your cache, or temporary internet folder, through the Options in your web browser. Your browser saves temporary files to your hard drive to speed up the loading of web pages. When the directory or folder containing that information is full, Acrobat pages will not load properly.

• Check the version of Adobe Acrobat Reader you currently have installed. Using Adobe Acrobat version 4.0 or above provides consistently good results in viewing PDF files.

• Some users have experienced difficulty in viewing PDF files with Internet Explorer version 5.0 and Adobe Acrobat Reader. Try downloading the PDF file directly to your computer, then close your web browser and open the document from your hard drive. 

Printing PDF files: 
Difficulty in printing a PDF file is not usual in the majority of printers. However, here are some quick tips that may help resolve problems you may have.

Large spool files when printing from an Acrobat 4.0 Viewer to a Non-PostScript Printer

Issue
When printing to a non-PostScript (i.e., PCL or QuickDraw ) printer, Adobe Acrobat 4.0 viewers generate very large print spool files. For example, if you print a 60K PDF file to a Hewlett-Packard DesignJet, your Acrobat viewer may generate a 298 MB spool file.

Solution 1
If you're printing in Windows, obtain and install a printer driver from the manufacturer that's specifically designed for that printer, then print using that driver.

Note: Some manufacturers, such as Hewlett-Packard, do not create printer drivers for all of their printers. Instead, they instruct you to use the printer drivers included with Windows for some of their printers. If your printer doesn't have a printer driver designed for it, Acrobat viewers may be unable to print to it without generating large print spool files.

Solution 2
Select Print As Image in the Print dialog box.
When you select Print As Image in the Print dialog box, your Acrobat viewer prints PDF files as bitmap data. Non-PostScript printer drivers may be able to print this bitmap data without generating unexpectedly large spool files.

Solution 3
If you're printing multiple pages, print fewer pages at once.
If printing a multiple-page PDF file overloads your printer (and crashes your system), or is excessively slow, try selecting one page at a time for printing, rather than trying to print the entire document at once. Some reports indicate that this is actually faster as well as less prone to crashing.

Solution 4
Deselect the Fit To Page option in the Print dialog box.
The Fit To Page option ensures that PDF pages, whose dimensions are larger than the printer's printable area, do print -- the Acrobat viewer scales them to fit within the printable area. This scaling can result in a larger spool file size. When you deselect this option, the Acrobat viewer doesn't scale PDF pages when printing them.

Solution 5
Print to a PostScript printer.
When an Acrobat 4.0 viewer prints to a PostScript printer, it sends its own PostScript code Therefore, it has direct control over how the PostScript spool file is created and how large it is.

Additional Information:
When an Acrobat 4.0 viewer prints to a non-PostScript printer, it must use the printer driver to convert the information to a format the printer can recognize. To aid the conversion, the Acrobat 4.0 viewer sends image data, which is banded, to the printer driver. (Banding breaks up a single large image into smaller, bit-size images that are easier to handle.) A non-PostScript printer driver converts this data to driver-specific spool information, and then scales and further bands the data. Depending on how the printer driver converts, scales, and bands the data, the spool file may be much larger in size than the PDF file the Acrobat viewer is printing. For example, the LaserJet 4000-series printer driver generates multiple copies of the banded images when converting the data, which greatly increases the spool file size. The size of the spool file is unrelated to the size of the PDF file.

Also, when you're printing in Windows, a Microsoft printer driver may enable you to print to a printer for which it wasn't specifically designed, but the driver does not contain printer-specific information (e.g., available memory) that can optimize printing. Therefore, a Microsoft printer driver not designed for a specific printer may generate unexpectedly large print spool files when printing a PDF file from an Acrobat 4.0 viewer. These large spool files can cause PDF files to print slowly or not at all. A printer driver designed specifically for a given printer can usually print a PDF file from an Acrobat 4.0 viewer without creating an unexpectedly large spool file.

In Mac OS, some QuickDraw printer drivers (e.g., Epson Stylus 900) may also generate unexpectedly large spool files because of the way they send information to the printer: These printer drivers generate an image for each page, spool the image to the hard disk, then send that image to the printer. These images are usually much larger than the PDF file from which they're being generated. The size of the spool file is unrelated to the size of the PDF file.

Some objects and text in a PDF file don't print to PCL (i.e non-PostScript) printers

Issue
When you print a PDF file from an Acrobat 4.0 Viewer to a PCL (i.e., non-PostScript) printer, some lines and text do not print.

Solution 1
Change your printer driver's graphic mode setting to Raster. For more information, see the documentation included with your printer.

Solution 2
Change your printer driver's Graphics/Dithering option to Fine or Coarse. For more information, see the documentation included with your printer.

Solution 3
Change the resolution setting for your video display driver to a higher resolution. For more information, see the documentation included with your video card, or contact Microsoft Technical Support.

When you print from an Acrobat 4.0 Viewer to a non-PostScript printer, the printer driver rasterizes graphics and text directly from the screen and the quality of the output is dependent on your video display driver. Depending on the resolution of your video or printer driver, some thin lines and text may not print as expected.

Solution 4
Print the PDF to a PostScript printer.

Because PostScript is device independent, you get the same output from any PostScript device, regardless of printer or screen resolution.
