Thank's to Broni, I just shook a nasty Trojan virus! However, now that's all taken care of -the printer is not working. The printer is a HP Officejet J650 All-in-One It prints, scans, and is a fax machine. When I go on Microsoft Word and type in "testing" on a document and hit 'print' the printer will print my sheet out no problems. However, if I try to print a picture or pdf. file, this error message pops up. For Pictures: For Pdf files: I have uninstalled and re-installed the printer's hardware. Made sure the printer's spooler is working (that was an issue once a couple months ago). Set the printer as the "Default" and made sure everything is plugged in correctly. Like I said, it will print perfectly fine if I go on Microsoft Word > Edit > Print > Print and when it brings up the screen with all your print options I have to go up and select the 'printer name' in the drop down box. So, my guess is that the other programs are not picking up on the printer by themselves because on Microsoft Word I have to manually select it. Any ideas on how to fix this? Any input would be greatly appreciated! Thank you!
