Advice solicited on cost-effective easy-to-use printer

A friend of mine is not computer savvy, and just wants to make prints off Compact Flash and SD cards without having to use a computer, and with the convenience of at-home printing. I set up an Epson RX580 for that purpose, which works great, but the cost per print is outrageous. Originally, I thought the volume of printing would make it reasonable, but it’s looking like thousands of prints will be made.

So—any reader suggestions on a printer that makes high quality prints at reasonable cost? (Print quality should be as good or better than the Epson RX580). It must be reasonably compact, and it must take Compact Flash and SD cards and have a user-friendly screen and menu system to operate it. Please email me as 'printer' at diglloyd.com.
