Do you need HP's PCL or Adobe's PostScript? Support for one or both of these two page-description languages (PDLs) is critical for those who need it, but otherwise irrelevant. PCL was once standard for business users, and is still required in some cases, but is not usually needed. PostScript can be essential for pre-proofing commercial print jobs, particularly in concert with desktop-publishing applications that won't work without it. It also guarantees that when printing a document, page breaks and line breaks will be the same when printing on any PostScript printer, and also the same as you saw on screen, assuming the program was set to use a PostScript driver. (Converting it to PDF format serves the same purpose.)

Generally speaking, if you're in a position to buy a printer for your business, you should already know if you need one or the other of these PDLs. If you don't need them, you can often find an identical or similar model for less from the same manufacturer, minus only the PCL or PostScript support. Don't pay extra for it if you don't need it.

LED printers are laser printers' fraternal twins. Both are electrophotographic printers, which means they print by using light to draw images to be printed on photoelectric material, which attracts particles of toner to be transferred to paper. The only difference is the light source: LED or laser. LED models tend to be somewhat smaller than directly comparable laser printers, which makes them particularly suitable where space is at a premium. But for purposes of comparison, they are essentially variations on a theme, a distinction with little to no real-world difference.

Key printer players that offer LED-based models (as well as laser ones) include Brother and Xerox.
