When I try to print with my canon IP1800 a message keeps coming up saying quot;port in usequot;? -

I ve checked the printer status and it seems fine, what am I doing wrong?

What connection interface did you use? is it USB or LPT printer port? if Printer port, maybe you already use a program that use printer port, like m-connect or another program. Try remove the program. http://www.manualforfree.com/2009/04/can…
