» How HP measures printing speed
HP inkjet printer speed specifications cover various types of printing. For example, 4 x 6 inch color 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, Color Text, Black Graphics and Color 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 color text pages is approximately 4 percent of the printable area (excludes margins) of the suite of test pages. Ink coverage of the color 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.

Seconds per Color Photo

Testing is conducted with the printer in draft or fastdraft mode (depending on the printer), unless otherwise specified, and uses 4 x 6 inch HP Advanced Photo Paper. Photo speed tests are conducted using Windows Picture and Fax Viewer Software. Ink coverage is equal to 100 percent of the printable area of the photo paper in bordered mode, unless otherwise specified.

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 photo lands in the output tray and ends when the second photo lands in the output tray.

ISO/IEC 24734:

Products introduced after Jan 1, 2009

ISO/IEC 24734 is an international standard for measuring productivity of both inkjet and laser printers. PPM testing is conducted using mixed content with the printer running in normal mode, unless otherwise specified, and using 8.5 by 11 inch plain paper. Tests are conducted using Microsoft Word, Microsoft Excel, and Adobe Reader. The average ink coverage of the test pages is approximately 11 percent of the printable area (excludes margins). Black tests are conducted with the driver set to print black ink only. See ISO test results for more information.

Tests do not include or measure processing time, which will vary depending upon the computer configuration, image, software, and connectivity. Timing excludes the first set of test documents.

Black Laser Quality Speed (LQS) and Color LQS Pages per Minute (PPM)

Products introduced before Jan 1, 2009

LQS PPM is the average of graphics PPM and text PPM with the printer running in normal mode, unless otherwise specified, and using 8.5 by 11 inch plain paper. Text tests are conducted using Microsoft Word; graphics tests are conducted using Microsoft Excel. The average ink coverage of the black and color text pages is approximately 4 percent of the printable area (excludes margins) of the suite of test pages. Ink coverage of the color graphics pages is approximately 65 percent of the printable area of the test pages. Ink coverage of the 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.

Black and Color First Page Out (FPO)

Testing is conducted using mixed content with the printers in normal mode, unless otherwise specified, and uses 8.5 by 11 inch plain paper. Tests are conducted using Microsoft Word, Microsoft Excel, and Adobe Reader. Ink coverage is equal to approximately 11 percent of the printable area (excludes margins). Black tests are conducted with the driver set to Grayscale Black Cartridge Only. A warm up page is sent to the printer prior to starting testing.

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.

Test Conditions and Equipment Used:

Printing speed tests are run in a normal office environment. Multiple tests are conducted to confirm the accuracy of the speed measurement. PPM may be rounded down. For example, if the test resulted in an average PPM of 27.4, HP may specify 27 PPM. Seconds may be rounded up. For example if a test resulted in an average of 14.5 seconds, HP may specify 15 seconds.

As of January 1, 2009, for Deskjet and Photosmart products, HP uses a notebook PC that includes an AMD Turion processor, 2.0 GHz, using Microsoft Vista and a USB connection. As of January 1, 2009, for Officejet and Officejet Pro products, HP uses a desktop PC that includes an Intel Pentium 4 processor, 3.4 GHz, using Microsoft XP and a USB connection. If multiple input trays are available, all testing is done using the main input tray, unless otherwise specified. Speed tests for copying and printing directly from a memory card are tested in a similar manner as specified above. If required, the software interface is used to set the number of copies. Copy speed tests are done without the use of an automatic document feeder, unless otherwise specified.
