You can sell you prints on deviantart.com . I have an account there but I've never gone about selling prints. So, its up to you to figure it out from there xD
the printing service on DA doesn't have much of a profit margin, or can you change that? However, a lto of DA artists do print their own and sell them on their DA profiles. If you're serious about selling your art for a decent price you should probably look around for a printers place to get a good quality print and paper. If you're looking to sell your work more cheaply you could probably use something like you suggested.
Any suggestions anyone else?
You can change the dA prices if you have a Premium Prints subscription - about $25 a year. Even then, though, the profit margin is a little wonky, they have a really low base price but they take 50% of the markup as well. I have an account on another site, Imagekind, and they have a way higher base price but the markup goes all to the artist.
OP: I'd suggest using a professional printing service designed for artists, the quality of the paper and print job is way better than anything you'll get at home or even at the local copy place (Most copy places are designed for businessmen to print up huge stacks of business plans or a few informative posters. Staples does
not print on sixty-inch pieces of canvas.)
There's a
comparison chart for selling art on Empty Easel, which includes a few printing services (Imagekind, RedBubble, and Artist Rising), and i've heard good things about
DPC Prints and
BlueFlip Art as well. I haven't looked much into DPC/BlueFlip, but Imagekind, RedBubble, and Artist Rising are all free, at least for a basic account.
