[xubuntu] Canon LBP 3250

Hi,

I am using Xubuntu 16.04 32-bit on Dell Vostro 200 and I'm trying to use Canon LBP 3250 printer.
I have tried so many steps, read many pages, etc but until this very moment, nothing happened. My system is not detecting the printer.

How can we fix this?

Yes, I did so many searches and checked AskUbuntu, etc but then again, didn't really find anything that could fix my issue.

Many thanks!
