It's a bit more subtle than that, because it depends on the printer (the previous answer is correct in the case of the original poster's 7900)... The Epson 7900 and 9900, plus their close cousins the 7890 and 9890 have a rotary cutter specifically designed to cut canvas.The 17" 4900 appears to use a different rotary cutter, but probably also cuts canvas. All older Epsons, with the possible exception of 60" models, used a blade (non-rotary) cutter that will dull almost right away if used on canvas. I'm almost certain that the Canon iPF 8300 and 8400 (and probably older 44" and 60" models) have a rotary cutter, but most of the smaller iPF series do not (automatic cut is actually disabled on canvas and other thick media), with the possible exception of the 6400. The most common HP DesignJets, the Z3100 and Z3200, have a blade cutter, and are not designed to cut canvas. Generally, the wider and newer a given printer is, the more likely it is to cut canvas correctly (I am not aware of any 17" printer other than the Epson 4900 that does cut canvas, nor of any 60" model that does NOT).
