Smaller Photo Printer Opinions? Please Respond It For Our Anniversary!

I had been thinking about a anniversary gift for my gf for a while now and finally came to the conclusion on buying a photo printer since she likes scrapbooking and creating albums for photos. I decided on photo printer rather than a camera mainly because we shoot most photos on our phones since it's more convenient and would like to have the option to choose which photos we want to print since a polaroid camera doesn't really give you that option. I have looked at some printers already like the Instax printers by Fujifilm, Canon Selphy, and was looking for something more along those lines. Here are some of the criterias that I want to hear about they don't have to meet all of them but please give your best opinions!

1. Decent Photo Quality that Will Hopefully Last

2. Versatile in Photo Print Sizes (Would Like to Giver Her Variety)

3. Size (Was looking for Something Similar to The Instax Mini Printer or Canon Selphy)

4. Able to Connect to Various Devices (Phones and Computers)

5. Affordable Price Per Print

6. Of Course Good Price to Value Ratio
