This printer was working fine. I got a new computer and installed the latest HP all in one drivers from the web, device was recognized and test page was OK. I noticed it wouldn't print from windows applications. It would start and just eject a blank page. The windows test page also resulted in a blank eject. The HP toolbox can talk to the printer and *it* prints the diagnostic page fine. Scan and copy from the panel works fine, and get this: there is a networked Linux printer and it prints out fine to the shared windows printer! It is not a cable or hardware problem. I also have a networked Lexmark printer and lexmark software. There is a printer on a lan switch (not attached to any computer) This printer works fine. I tried the HP uninstall applet and reinstalled. I reverted to the original drivers from the CD that came with the printer. No luck. I installed HP 550c drivers from windows and this allows me to print. I am running up to date WIN XP home SP2. ___________________________________________ How can a Linux box work as a SMB share but not the local printer? Why does the 550C driver work, not the 166MB HP download? Why does the HP toolbox test page work, but anything from a windows application or the test page just turns up a blank? Could there be a conflict with Lexmark drivers? Before I had both coexisting on an old computer running XP PRO. Thanks for any help!
