Pretty well any modern printer which claims to be "photographic quality! will do. If it can handle thick high quality paper. Multiple ink cartridges are a plus if you do a lot of printing. You just buy the colour you have used up, not a set of three in one cartridge. It must accept thick paper at one side and discharge it at the other, it won't go round a roller system.
This brings up my only real unresolved problem with ArtRage.
To achieve the various wonderful effects, such as Paint texture and Glitter, the picture is "virtually lit" from the top left hand corner.
Real World paintings are not.
Prints therefore emerge as if they were already lit.
I have had various problems with this on three different printers.
Also, once it in a frame and sold the light can come from anywhere
I would like the ability to turn off the "virtual lighting" It would lose the texture effects and brush marks, but it would also lose some of the anomalies. This can be done in the Colour sample menu to get identical colour picks, but not as a feature.
Try something which uses Glitter through your existing printer and see how it turns out. I have stopped using it for leaves.
Luck is infatuated with the efficient.
