Thermal Printers Suited For Receipts, Work Orders and Simple Jobs

A thermal printer like this one is typically used for situations where simplicity is the highest priority: a portable printer, for example, or a printer for receipts, work orders, or other forms. It uses specially coated paper that changes color when heated. Most thermal printers change only to black, but bicolor models can create two colors depending upon the temperature applied. A thermal printer cannot mix colors or create shades of colors, so it's best used for text documents or extremely simple graphics.

Fax Capability Saves Space in Small Offices

This printer can also be used as a fax machine, a feature you'll find on some multifunction models. If you frequently send faxes, having a device that does both can save space in a small office. This printer may have just one phone jack for faxing, or two so it can also be used to place calls via a handset. 

If faxing features are important to you, pay attention to fax-page and speed-dial memory -- 100 is the common capacity in both cases. Also look for fax transmission speed, resolution, and perhaps the ability to fax to networked computer.

Compatible with Both Apple and Windows Operating Systems

Printers such as this model are compatible with computers designed by Apple that run either Mac OS X; or computers that use Microsoft Windows. In addition to having at least one appropriate connection for each computer platform, it should also come with drivers written for both operating systems.

Be Skeptical of Color Print Speed Claims

A printer's stated color print speed (expressed in pages per minute, or "ppm") should be taken with a grain of salt. Vendors often use contrived methods to arrive at such numbers. For instance, they might print in draft mode, which is faster than the default mode most people use. Or they'll exclude the first page out from a document's total print time, because its slower exit reflects the processing time needed to create the document image for the printer. Or they might send raw data straight to the printer, bypassing any application or PC processing time. The PC World Test Center uses dedicated testbed PCs and real-world applications to reflect actual use as closely as possible. We also time the document "from click to clunk" -- from the time we click the "Print" button to the time when the last page falls into the output tray.

Take black-and-white print speed times with a grain of salt

A printer's stated monochrome or "black-and-white" print speed (expressed in pages per minute, or "ppm") should be taken with a grain of salt. Vendors often use contrived methods to arrive at such numbers. For instance, they might print in draft mode, which is faster than the default mode most people use. Or they'll exclude the first page out from a document's total print time, because its slower exit reflects the processing time needed to create the document image for the printer.

Medium-Resolution Scanners Keep Enlargements Clear

This scanner's optical scan resolution is midrange. In addition to scanning typical documents or photos at actual size (300x300 dpi or 600x600 dpi suffice for such tasks), it can also use these higher resolutions to enlarge such items digitally with good results. The image-file size also gets bigger, of course, so make sure you have enough storage space.
