I do make art prints from canvas rolls using the Epson Workforce 1100. Not designed for canvas, but it can be made to work.

I cut the canvas with a long straight edge and a utility knife with the canvas on a cardboard sheet. The major problems you will have, depending on the printer, are curl and small fringes where you have cut the canvas.

Curl is easy to fix. The printer likes it to curve away from the center roll so after you've cut it just roll it that way and hold for a few seconds.

The fringy edge is hard- depending on how clean your cut is sometimes it will feed properly and sometimes not. Generally the solution is to use some thin paper tape over the leading edge of the canvas - sometimes it will work with just a strip of paper folded in half and put over the leading edge. I also have some cardboard sheets that I put in the paper feed area behind the canvas. It can take a few tries before the printer decides it will print.

So, it can be done, but isn't blindingly easy - probably will vary in difficulty with printer type.

Good luck,
Graham
