Job completed but didn't print

[Syazwan]

Hello, I have this problem that my printer Canon PIXMA iP1000 doesn't print although it is detected by cups (i.e. CUPS detects when my printer goes on/offline). When I send any jobs CUPS will report job completed but the printer did nothing.

I've tried printing with command line lp too but to no avail. Can anyone point me in the right direction?

And uh, I got my .ppd file from random search on Google, if that matters.
