Welcome to Vista Forums!
If the above doesn't work, try bypassing the print spooler and printing directly to the printer. It's not as efficient, but sometimes this will solve the problem. Although it varies somewhat by printer, this is typically done by going to Start / Control Panel / Printers. Select the printer and right click on it and click Properties. Go to the Advanced Tab. There will probably be an option to spool print jobs or send them directly to the printer and it will most likely be set on spooling jobs. Change this to print directly to printer and see if that helps.
As far as PDF files go, often times an Adobe PDF file may cause errors with PCL drivers. They often work best with PS (PostScript) drivers (but those are not available for this printer model). If you are trying to print an Adobe document, try the following: go to File > Print...Click the Advanced button. Put a check mark in Print as Image. Try printing the document that way and see if it works, helps, and is still as clear as you want it to be.
If that doesn't work, try updating and/or re-installing the Dell print driver: Drivers and Downloads
even if Device manager says it's OK and it's the same version that you already have - it's possible it is slightly corrupted - not enough to show up as a problem or prevent most printer functions, but enough to cause these special problems. In any event, doing so cannot hurt even if it doesn't resolve the problem (but then again, it may do the trick). At this point, it's worth a try.
Also download and install the appropriate printer firmware: Drivers and Downloads
Finally, download and install the printer software for this Dell printer: Drivers and Downloads
Then test the printer and see if the situation has improved (or gotten worse). If the problem persists, check out the user manual for your printer to see if it contains anything that may help identify and resolve the problem: http://support.dell.com/support/edoc...n/ug/index.htm
. Especially look for settings on the printer itself (as opposed to on the computer) that may help the situation if reconfigured (but remember what they were so you can return them back to the original settings if changes don't work and/or make things worse).
I hope this helps. If not, post back and we'll do more research into the problem. For the time being, let's put the other printer problem on the back-burner until we've resolved this one.
