4 Printing speed measured using ISO/IEC 24734 and excludes first set of test documents. For more information, see Exact speed varies depending on
the system configuration, software application, driver, and document complexity. First page out exact speed varies depending on the system configuration, software program,
document complexity, network, media width, media weight, environment, and job size. 5 Requires an Internet connection to the printer. Services may require registration. App
availability varies by country, language, and agreements. For details, see 6 HP LaserJet 255X Black Toner Cartridge not included; please purchase separately. 7
HP Smart Install works with Microsoft Windows only. 8 Local printing requires mobile device and printer to be on the same network or have a direct wireless connection to the
printer. Wireless performance is dependent on physical environment and distance from access point. Wireless operations are compatible with 2.4 GHz operations only. Remote
printing requires an Internet connection to an HP web-connected printer. App or software and HP ePrint account registration may also be required. Wireless broadband use
requires separately purchased service contract for mobile devices. Check with service provider for coverage and availability in your area. See for more

printing conditions and usage.And users can also purchase CE255X cartridge for this printer,which declared yield is 12500 pages basing on ISO/IEC 19752. 2 Values subject to change. Power numbers are the highest values measured using all standard voltages. See for current information. Power requirements are based on the country/region where the printer is sold. Do not convert operating voltages. This will damage the printer and void the product warranty. 3 Approximate average yield based on ISO/IEC 19752. Actual
yield varies considerably based on printer platform, content of printed pages and other factors. For details see 4 Based on standard ITU-T test image #1 at standard resolution. More complicated pages or higher resolution will take
longer and use more memory. 5 Measured using ISO/IEC 24734, excludes first set of test documents. For more information see Exact speed varies depending on the system configuration, software application, driver, and document complexity. 6 Exact
speed varies depending on the system configuration, software application, driver and document complexity. 7 Scan speeds of up to 21 ppm measured at 200 dpi (b&w) and up to 15 ppm at 200 dpi (color) from automatic document feeder when scanning to digital file. Actual
speeds may vary depending on scan resolution, network conditions, computer performance and application software.
