I am a N0ob of Linux. But after two days trail and error, I finally managed to get CUPS working on mybook.
I added my Canon MF4140 from the CUPS webpage, shared it on local network. I also installed the PPD file from Canon.
I was almost there. Now the issue is that the printing job never got passed to the printer. They are always in pending status,
no matter I tried to print a test page from CUPS or print a real doc from connected windows client.
I am thinking this might be a driver issue. So I decided to install the offical driver from Canon. However the driver is packaged by
rpm. When I tried to launch rpm, I realized it's not in the system. My question is how can I install rpm itself on Mybook, therefore
I can install the .rpm Canon driver.
