I've got a strange situation - I cannot print a PDF file from an XP machine on a Canon i320 printer. I can print any other format on the XP and Canon i320, and I can print the PDF on the XP with other printers, and I can print a PDF file on the Canon i320 if I use a Windows 98 or a Windows 2000 machine. Is the problem with XP or the Canon i320 or the PDF format?!? Not sure where to start with troubleshooting here............
