Printer

[kevin_aj2001]

how can I finding exact amount printing of a specific cartridge?

 

[hang-the-9]

From the vendor of said cartridge. Or print till it's empty, and count how many pages you used. Or weigh a piece of paper, then weigh it after printing, and divide the amount of ink in the cartride by the weight difference between the unprinted and printer paper.

I'm going to bet you will pick the first option I posted.
