HP printer speed specifications cover various types of printing. For example, 4 x 6 inch colour photo print speed tests are very different from 8.5 x 11 inch black text document tests. Below are explanations of various types of printing and the speed testing methodology for each. |
|
|
|
Black Text, Colour Text, Black Graphics and Colour Graphics Pages per Minute (PPM) |
|
|
|
Testing is conducted with the printer in draft or fastdraft mode (depending on the printer), unless otherwise specified, and uses 8.5 x 11 inch plain paper. Text tests are conducted using Microsoft Word; graphics tests are conducted using Microsoft Excel. The average ink coverage of black and colour text pages is approximately 4 percent of the printable area (excludes margins) of the suite of test pages. Ink coverage of the colour graphics pages is approximately 65 percent of the printable area of the test pages. Lastly, ink coverage of black graphics pages is approximately 6 percent of the printable area of the test pages.
Tests do not include or measure processing time, which will vary depending upon the computer configuration, image, software, and connectivity. Timing begins when the first page lands in the output tray and ends when the last page lands in the output tray. Multiple tests are conducted to confirm the accuracy of the speed measurement. PPM results are rounded down. For example, if the test resulted in an average PPM of 27.4, HP will specify 27 PPM.

Timing begins with pressing "OK" in the print dialog box and ends when the first page lands in the output tray. This test does include and measure processing time. Multiple tests are conducted to confirm the accuracy of the speed measurement. Seconds are rounded up. |
