Printers

Can print automatically on both sides of the paper.

Lets you automatically load multiple-page documents into an all-in-one printer for scanning or copying.

Can scan and copy automatically both sides of the original document.

For an all-in-one printer, a built-in fax modem that lets you fax what you've scanned without the need for assistance from the computer's own communication hardware.

Most inkjets use a separate cartridge for each ink color. But some models instead have a tri-color cartridge that supplies three colors from one unit. Individual color cartridges allows you to individually replace only the color that runs out, rather than tossing out a tri-color cartridge that may have some ink left.

Refillable ink-tank inkjet printers dispense with pricey replacement cartridges in favor of refillable reservoirs replenished with a bottle of ink.

Most all-in-one printers have a glass scanning bed with a lid you can fully raise in order to scan books and other thick media as well as flat originals. Items scanned can also be faxed. But some models, usually portables, use a sheet-fed scanner which is trickier to use.

Can still print (usually in black and white only) if a color ink cartridge runs out. May require changing a setting, and leaving the empty cartridges installed. The printer may offer this option for a short time only. The option may not appear at all unless you've first installed the printer's full software package.

The photo ink for some inkjet printers comes in an extra cartridge. To use these photo inks, you must remove the black-ink cartridge and replace it with the photo-ink cartridge. To go back to printing text or graphics, you must do the reverse. This can get tedious. Models that hold all the inks simultaneously minimize the hassle.

This feature lets you print photos that go edge-to-edge without a white border.

Can print automatically on both sides of the paper.

Indicates whether the printer has a built-in memory-card reader. If so, this feature lets you print image files from a digital camera's memory card without using a computer. You can also transfer the files to a computer.

When printing on glossy photo paper, water-resistant ink will not run or smear if it gets wet.

Printer has a built-in LCD screen for viewing and editing images from a memory card. The screen is small, usually only 1 to 3.5 inches, and editing capability is very limited.

Most inkjet printers use a separate cartridge for each color. Others have tri-color cartridges with three colors in one. Individual color cartridges let you replace only the color that runs out rather than tossing a tri-color cartridge that may have some ink left.

Models are directed at specific segments of the consumer market. The SOHO or Small Office-Home Office type model is intended for higher-volume printing than the Personal type.

Indicates which technology a printer uses to create an image onto paper or other media. Most printers use inkjet technology, printers intended primarily for text use laser technology.

How many sheets of standard-thickness (20-lb.) paper can be stored in the printer's input tray.

Measured in inches, the height of printer when it is open and ready to use, with trays extended and paper in trays.

Measured in inches, the width of the printer when it is open and ready to print with paper loaded.

Measured in inches, the depth of printer when it is open and ready to use, trays extended and paper in trays, and allowing for rear connectors.

Our measure of how fast the printer can print pages of monochrome text.

The ink-related cost of one page of black text.

The cost of printing one page of a colorful chart or web page, in cents.

4x6 photo cost per print.

8x10 photo cost per print.

The maximum size paper which the printer can accept for printing.

All printers can accept standard-thickness/stiffness paper, referred to as 20-lb. basis weight. But many accept thicker/stiffer paper. The basis weight actually corresponds to paper density, which affects thickness and stiffness.

Which operating system(s) will support a given printer. Most printers can work with both Windows and the Macintosh, although models differ on which versions they require.

The number of cartridges or tanks of ink or toner that the printer requires. Some printers which promote photo-printing may use more than 4 cartridges.

The number of colors of ink or toner that the printer requires.

Estimated cost (in dollars) for ink or toner in a month of typical use, based on our tests and how our readers told us they print. For inkjets: 23 text pages, 9 graphics pages, 2.4 large photos, 3.6 small photos, and 3.5 photos on plain paper. For lasers: 62 text pages, 24 graphics pages, 1.7 large photos, 1.9 small photos, and 2.3 photos on plain paper. Photos cost the most, text documents the least, so your results may vary from these figures, but they are useful for comparing models.

The printer may connect to a home network either via an Ethernet (E) or a WiFi (W) connection. Ethernet is the common wired network and WiFi is the wireless format commonly found in laptop computers. Many printers also support Apple AirPrint (A) allowing you to print from local Apple devices.

An installation feature that links a printer to a home network by copying the settings from a computer that is already linked to the same network. Avoids typing passkeys and pressing WPS buttons.

Provides a wireless connection for local printing from a mobile device like a smartphone, even if the printer and smartphone are not joined to a home network.

This feature allows direct printing (without the use of a computer) from any brand of digital camera to any brand of printer. It relies on a USB connection. More recently, Wireless PictBridge has appeared on some models.
