How much you thinking of spending PW, makes a big difference to what you buy.
You talk about size of print, but not whether they are actually on photo paper? I ask cos nowadays you can get colour laser printers at a very decent price.
Ignore what Paul says, Epson are usually the brand to go for when buying colour inkjet that can be used to print photos (on photo paper - makes a big difference to the quality of the print too).
