With entries from HP, Olympus, Sony, Epson, Canon and others, the market for sub-$200 4"x6" photo printers is pretty crowded. While we can understand the appeal for some people — especially for printers with built-in LCD displays, direct memory-card printing and battery power like the HP PhotoSmart 375 — we think most of these are a little too limited for anyone whose digital photography needs go beyond that of the casual snapshooter. PC Magazine took a look at Canon's offering, the Selphy DS700, which ditches the LCD display for a TV jack. While they found the TV connectivity straightforward, they found most of the printer's other features to be just average, and pointed out its obvious Achille's heel: when you're away from your TV, you've got no preview options. They also found the printing costs to be pretty steep — as much as 72-cents per print, compared to the 29-cent price that some other printers claim.
