After reinstalling the drivers and checking for updates, which are current, I'm still haveing problems printing from my CAD program Vectorworks Fundamentals. When I send a document to print the system hangs on "spooling". I can delete the file only after shutting down the CAD software. All other programs print fine. I've contacted the software company and they are at a loss. I have a Photosmart C310 connected to the same computer and I can print without issues. I'm running Windows 7 - just recently installed - and all updates are current. Also, the CAD service packs are up to date. What is mysterious is that in the HP solutions program it shows that the L7500 series printer is disconnected. I was getting this message frequently when running Win XP too but had no issues with printing from any program. I open the printer toolbox and it says "the computer is unable to establish a two-way communication with the device". Just to test, I can go to a program, say Excel, and then print a document without issue. Then going back to CAD, trying to print causes the printer to hang on spooling again.
I've shut the computer and printer down, unplugged the printer and restarted, still the same situation.
I did not have this problem running XP. My only way to print a CAD document now is to save as a PDF and then print from there which it does fine - even though HP Solutions says the printer is disconnected.
Any solution would be appreciated. What is this scrubber that I saw on another trouble shooting posting?
