Best Printer for diy invitations

Hi all!

So I'm trying to find the BEST printer for printing my own invitations (no budget restrictions). I'm using pocket invitations so I'll be printing on four pieces of 5" x 7" 80# card stock per invitation (thinking about 50 invitations). I have found several suggestions on other discussions of places to get them printed, but I really prefer to print at home and we need a new printer anyway. I'm hoping to find a printer that can print on various sizes of paper, print on 80# paper clearly with no jam, is easy to order more and replace ink cartridges (preferably on amazon!) and is a double sided printer (in one pass). Hopefully it can also copy and scan. I'm thinking this is a dream printer! But if anyone has any suggestions that would be great, thanks so much!
