I also make greeting cards and print onto card. I have a Canon Pixma MP600R, it handles card with no problems at all, it also has the benefit that the ink cartridges are individual colours so that if you print a lot with one colour, you only need to replace that cartridge. I think this also works out less expensive compared to other systems. My model is also wireless, so can have it in my craft room, but some distance away from the pc which saves room on my work desk.
