I have a Canon Maxify 2750. Up until now I’ve been using the standar linux drivers for it but they have a serious limitation I really need to solve which is I can only print one page at a time, on one sheet of paper. Printer is capable of full duplex printing. If been able to install the drivers before but now I’me being confronted with an unexpected _“(”_ error. Nothing more, nothing less. I run the install script and it just fails. Can someone lend a hand on this, please?
