PRINTING. The Dell E525w prints using laser technology, which picks up powdered 'toner' on a roller and fuses it to the paper with heat. It prints Good color photos that are fine for casual users, typical performance for a laser printer. Its text quality is Excellent, as we've come to expect from a laser printer. Text printing was very quick, 11.1 pages per minute, costing 12.8 cents per page. It prints color graphics such as charts and web pages beautifully, in presentation-quality, with no noticeable defects, at 4 pages per minute, costing 25.9 cents per page. If any color ink runs out, it stops printing—it can't be set to just use the remaining black ink. If the black ink runs out, it stops printing—it can't be set to just use the remaining color ink. The capacity of the main paper tray is 150 sheets, a typical size.
SCANNING and COPYING. Scanning performance was Very Good, fine for general-purpose scanning. It can scan or copy an area up to 11.7 x 8.4 inches (letter size). Copying performance was Very Good, suitable for most purposes. It has an Automatic Document Feeder (ADF) for easily scanning/copying a stack of pages.
CONTROLS and DISPLAY. The printer has a large, 3.2-inch display screen.
CONNECTIVITY and NETWORKING. You can connect directly to a PC with a USB cable, or to your network router either wirelessly with WiFi or with an Ethernet cable. Apple AirPrint and Google Cloud Print are built-in, to print wirelessly from smartphones, tablets and PCs. You can also install Dell's app on your smart phone or tablet, as another option for printing over your WiFi network. This model has built-in faxing, can store incoming faxes if the paper runs out, and can send faxes from an attached PC.
COST OF OWNERSHIP AND TONER. When this section was last updated, the printer's purchase price was about $215, very cheap for an all-in-one color laser printer. Printing uses up toner. Over time, as you print, the costs add up. This printer uses 4 cartridges. The Dell toner cartridges used in testing were the DPV4T, H5WFX, 3581G and G20VW. At the time, their prices were all $66 each. We estimate the toner cartridges to last an extraordinarily long time -- around 28 months -- following a typical printing schedule. After 2 years of typical use, we estimate the total cost to be $671, high for a color laser. The estimated yearly cost is $228, very high for this printer type. So the 3-, 4- and 5-year estimates are $899, $1127 and $1355 respectively.
PRINTER FIRMWARE. Firmware is software that exists inside the printer. All models are evaluated using the latest firmware version available at the time of testing. The firmware version of the Dell E525w was 01.00.05.10.3836.

These get installed on your personal computer. All models are evaluated with a Windows 10 PC using the latest version of printer driver and printer support apps available at the time of testing. The software version was 1.0.1.6.
