Ken, Canvas, comes as canvas, coated on one side to take the inks. It goes through the printer as is, no need to fix it to anything!

The Hahnemule papers are good, and competitively priced, I personally use Crane Museo paper.

The main thing to look for when comparing printers, in my mind is how they print black, take samples into various types of light and look for tint in the black, it is this that really makes a difference between various printers.

Good Luck
