I have tried a laser printer, not treated the fabric [cotton sheet from thrift shop]

and it was great [guy at post office helped-as it was the shop printer and i had to pay of course about 60p a A3 size print ] backed with freezer paper

came out great and i washed it in washing machine [with some dark towel ...in case the colors ran , but it came out looking as good as it did before being washed

also tried inkjet not bad - but def not washable, faded to very pale black with no colors i was really disappointed-i would buy a laser printer-but they are so large [as i would want an A3]

i even tried a homemade pre-treatment [on the net] took time and results were abysmal and almost all of it washed away

i think the laser printing is beautiful [though check your colors i as the guy in post office sharpened up my pics and density and lightened them up a tad-what a difference that made

so........

i would only use inkjet -if i never intended to wash the printed piece -end of
