File Size Increases in Spooler When Printing to a PostScript Printer with Kernel and User Mode Drivers


When you try to print a file that contains TrueType fonts to a PostScript printer that uses User mode or Kernel mode print drivers, the print job size may increase beyond its actual size in the print spooler.


This behavior occurs because the font file mapping changes dynamically instead of being mapped in Kernel mode. As a result, the same font in different sizes is downloaded over and over again, causing the file size to increase.


To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows 2000 Service Pack 2.

More Information

The WHQL printer test kit, which is available at, has some tools that allow you to determine whether a driver is Kernel mode.

Another quick way to determine the mode is to install the driver and then check to see where the files are in the %WinDir%\System32\Spool\Drivers\W32x86 folder. If they are in the "2" folder, the driver is Kernel mode; if they are in the "3" folder, the driver is User mode.
