Hey, Mike-HP OfficeJet Pro Wide-format All-in-Ones | HP® Official Site
I have an older model that will do 13 x 19, the newer ones that are pigment are 11 x 17, but they have larger carts sizes and ink is cheaper that way.

I used to try to find some reasonably close coloured paper and print on that to get an idea of how an image 'might' look when printed on a similar coloured cloth. Some newsagents and even supermarkets sell small packs (about 50 sheets) of various red, green, blue, yellow and other coloured paper.' if you design to work with what the color does.'
