How do I print alternate page sizes on Windows XP or 2000?
When printing from an application, select the PDF995 printer, click Properties or Preferences and then click the Advanced button. Adjust the page size as required. If this fails, try adding IsXPor2000=0 to the Parameters section of c:\pdf995\res\pdf995.ini and run c:\pdf995\setup.exe.
