Hi ladies, I just wanted to give you a quick update, the Canon Pixma MG2220 I purchased did great for my passport invites. I used metallic cardstock and regular metallic paper from paperandmore. I did end up having to purchase a second color cartridge but well worth it. I printed about 80 invitations, 1 cover and 2 sheets, so an 8 pg booklet just to give you an idea of the amount of work.
Good luck to anyone still looking for a printer!
