Why is the first page blank when I print from OpenOffice?
OpenOffice.org (and also other PPD-aware applications or print filters) inserts printer-specific PostScript code into the PostScript output file according to the definitions of the options in the PPD file, so that the printer prints the document in the way the user has configured it by the options in the “Properties” dialog. These inserted PostScript commands are not generally understood by every PostScript interpreter (every printer has its own PPD file), so GhostScript does not need to understand them.
