I've got a problem in that while I can print to my HP Officejet 8600 OK with Micorosoft Office products etc. when trying to print Adobe Reader files (with version 9) the microsoft spooler apps subsystem crashes and I have to reinstall printer drivers to get things back to the way they were. I'm running Vista 32 bit home premium with service pack 1, and all updates/drivers for this and the printer are installed. HP helpdesk say the problem is down to Adobe rather than the HP software. Any suggestions as to what to do welcome.
