By the time you’re ready to print a photo, chances are you have optimized the image by adjusting your camera settings before you snap and maybe even Photoshopped it afterward. Now you have a third line of defense against bad photos: Canon has announced three new printers with technology that it says can resolve common photo-printing flaws.

The company says its two new Pixma all-in-one (print/copy/scan) devices employ Auto Photo Fix II technology to correct errors through exposure correction and improvements in face detection and scene analysis, plus brightness and saturation correction. The new Pixma inkjets also include software that enables users to target and print a specific area of a Web page, rather than printing an entire page (or pages), an eco-friendly option that will result in paper and ink savings.

The $150 Pixma MP560 Wireless2 Photo AIO Printer has built-in Wi-Fi connectivity and two-sided printing, another great way to conserve resources (although it will slow your print job). This new AIO Printer can print photos directly from a U.S.B. thumb drive, a new capability. (All the new Canon devices accept a wide variety of camera memory cards.) Canon says the Pixma MP560, which employs five inks, can deliver borderless 4-by-6-inch prints in about 39 seconds.

One step down is the $100 Pixma MP490 AIO Photo Printer, a four-ink system that can print a 4-by-6-inch photo about in 43 seconds. It lacks Wi-Fi connectivity but does include a U.S.B. slot for computer-less printing.

And for those who want to take a printer to the party, Canon has updated its Selphy line to include the $180 CP790 Compact Photo Printer. The CP790, like its predecessor, the CP770, comes in its own carrying “basket” (it looks more like a bucket, really) that houses the printer, as well as accessories like paper, ink cartridges and the power cord. Those who want to be truly mobile can also toss in an optional $80 battery.

Canon says the new Selphy yields better photos than last year’s model because of a new portrait-image optimization feature and face-detection brightness correction. The CP790 can output a 4-by-6-inch print in 43 seconds, according to the company.

The Selphy CP790 will be available this month, but you’ll have to wait until August for the new Pixma printers.
