Hi, I've used the HP Artist matte canvas 42 inch with good detail and colour after profilling. I think it automatically disables the cutter but just to be sure, I use the button in the driver to disable it too. The built in cutter cant cut it (excuse the pun!). You have to manually cut it. I just used scirrors and used the leading edge on the printer as a guide to keep it straight.
Loads back in for me but you have to make sure it's a straight 90 degrees cut!
cheers, Evo
Now gallery wrapping is a nother story!
