I don't get why it takes both QU and Canon to cancel a job and clear out the buffer. Seems QU should kill it off. Doing one or the other keeps the jobs running. Needs a "STOP ALL PRINTING NOW" emergency button to kill off everything.
Mack,
This has been a smiley hair puller for years and years.
Once Qimage or any program that produces a print file is finished, the print file goes to Windows print spooler.
The program; Qimage or email; or a Word Processor is DONE!
What windows and your printer do from that point on is not controlled by the software that produced the file.
All of us have been down this road... You turn off the printer, reboot the computer, turn them on, and the sucker still prints sometimes just junk characters.
You have to go into Printers and devices, click on your printer, highlight the job, Click File and delete pending print job.
Sometimes, it refuses to delete right away. Then when you reboot, the print spooler will/should be empty. Restart the printer and all is well..... but all those sheets of paper waster.... turn them upside down.
Really, Mack! I'll bet there isn't a person on here that hasn't had this happen.
Join the club!
