Hi mhesha medda - Welcome to w7forums
I moved both of your post to this new thread. Your printer had nothing to do with the other two threads. It is always best to start a new thread with a new problem. And its always nice to the other members if you don't highjack their threads as one of them has not been solved yet.
I presume the Canon "
i-SENSYS LBP-2900" or "
Laser Shot LBP2900" is your printer.
Have you tried the drivers from these pages?
Canon CAPT Printer Driver (x86 - 32-Bit)
