I'm so interested in this conversation as we just got a new printer yesterday (Kodak one had very poor print quality). So I got an HP and the quality is much better but I was so disappointed to find out that the digi's smeared with my copics - even after I tried heat setting them and letting them sit overnight (though that was SLIGHTLY better). Judi (Crafts) said over in another thread that HP has two different inks available, "regular" and "photo", and she found that "photo ink" did not smear, so I'm adding that info to this discussion!
