Photo printer buying can be challenging. You need to look at speed, paper printing size, ink cartridge types and features. You need to decide if you want a compact photo printer, printer dock, combo printer or standard full-sized printer. Here are tips before you buy a photo printer.
Pick the Type of Photo Printer
You need to consider how you will use your photo printer. If you want to also be able to send faxes and scan pictures and documents, a combo unit is probably best.
If you simply want to print nice 4"x6" images easily and even while traveling, a compact photo printer is the best choice. If you do most of your printing in one place and want the option of 8"x10" prints, go with a standard full-sized printer. If you are a pro or want impressive prints in large sizes, go with a large-paper printer.
Decide on the Quality of Your Photo Prints
The dpi of a printer is a crucial aspect. If you will simply make lots of smaller 4"x6" prints, this isn't as important. But if you plan to do enlargments, particularly above 8"x10", you will want to examine and compare the print resolution. Look for at least 4800 dpi for larger photo prints.
Connecting to Your Camera, Computer and Images
Most printers now come with PictBridge to ease connection directly from camera to printer, and most connect to your computer with a USB cable. You should also consider other options that may be important. Memory card slots built right onto the printer are a handy option, but just be sure the printer accepts
Ink Cartridges for Photo Printers
The more ink cartridges your photo printer uses, the better quality the prints will be. This also means that when you run out of just one color, you won't be paying to replace all colors. On the downside, you will need to buy catridges more often because there are more that can run out.
