Printing from iPhone 7.1.2 via Airprint doesn't work on Canon D320 #5

Hi Ondrej, please tell me what kind of log might help you to resolve this: I have 3 printers 2 of them works fine, only Canon always gets stuck when I print via Airprint from my iPhone even if I use file based uri file://dev/canonD300 in the printer configuration.

The printer itself claims that there is no paper left (and of course there are plenty sheets of paper) and literally I need to turn off and turn on the printer from the electricity in order to make accept any other prints. When I print from Linux Mint 17 directly there are no issues.

Thank you for your help!

Best regards, Andrej

Make sure that the document paper size matches the size set on printer panel (LCD menus). If you, for example, send a job with letter format to a printer that is configured to A4, it will display an error on LCD and hang (this is true at least for MF5730). So change the output from file:///dev/something to file:///home/someone/somefile.prn, print something from the iPhone and then run carps-decode on the resulting file.

Hello Ondrej, thank you for your help and debug steps. If this would happen again I'll try to do it that way.

In the mean time I have figure it out. The wrong was the paper size that was set to the A4 format instead of US-Letter, that was in the printer. This small issues cause the whole thing.

Best regards, Andrej
