The little 4x6 printers that you refer to are gone from the market place. The idea was great. Shoot pictures, insert memory card, Print an index print and then print just the 4x6 prints you wanted. The quality was excellent! However the ink supply did not last and the ink cartridges are expensive.Do you shoot enough digital pictures to equal one roll of film (20-24 exposures) a week? Neither did I. I purchased one of these printers when they first came out @ $200.00. I found myself replacing the ink cartridge ($30) much sooner than developing 100 prints that the cartridge was supposed to yield. The result is, you, I, and others will have to go to our favorite one-hour processor, get a latte or shop until our prints are done. I saw these printers drop in price to $69.00 and then they disappeared from the market place.

You'll need a printer that accepts USB for direct transfer or accepts your style of memory card.However, I'd always suggest you upload and print from your computer. The reason is this. If you have photos that are out of focus, poorly lit, etc., you're going to waste a lot of printer paper finding this out.
