I have installed Samsung CLP-325 (USB) with official drivers from the manufacturer. Printing works fine, but print jobs are marked as "completed-successfully" even though nothing is printed yet. I have examined the problem and it seems that CUPS marks the job as completed directly after the printer receives it, but does not wait until it's finished.
I've tried the following:
- Take out paper from the printer so it cannot print
- Send a file for printing
- (CUPS marks the job as completed, but nothing is printed)
- Disconnect the printer from USB
- Add paper to the printer
- Printer prints the file
So obviously the job is accepted by the printer and then immediatelly marked as completed even though it's not finished yet..
Any ideas where could be the problem? Thanks!
