One of the biggest headaches with printers, especially USB printers, is getting a print job to stop once it has already started. Sometimes you can click cancel on the print job, but other times the job will go until completion. Even turning off the printer does not always solve the problem. I finally came across a solution that fixes all printing problems for me.
Step 1. If you need to immediately stop the printer from wasting paper/ink, turn off your printer. This may involve unplugging the power cord from the surge protector if the regular power buttons fail.
Step 4. Start > Run > C:WindowsSystem32SpoolPrinters
Step 5. Hit OK, and delete all files within the “Printers” folder you just opened. This will delete any print jobs you had remaining.
Step 6. Start > Run > net start spooler
Step 7. Hit OK, and turn your printer back on.
All of your printing problems should now be solved. Please post comments if this did or did not work for you.
