Can anyone please help?
I use Mac OS El Capitan and a Pixma iP8750 A3 printer.
I have a couple of very frustrating issues.
!) How do you enable double sided printing ( I believe it is also termed Duplex printing)?
I have read in the manual that the printer I have is not compatable with double sided printing using Mac El Capitan although Canon UK says that it can.
2) When printing images from Photoshop there is a series of thick lines through the image which gives the appearance of looking through a prison cell.
These lines do not appear when printing from Lightroom or the image garden and test prints are spot on.
