American technology company Hewlett-Packard has set an official Guinness World Records title for the fastest time to print 500 sheets by an office color desktop printer.

HP used its HP Officejet Pro X551dw single function printer and the multifunction version of the X576dw MFP with HP PageWide Technology to set the record in Vancouver, Washington, USA, on April 6, 2012. The record attempt was supervised and validated by testing and printing expert Terry Wirth of as well as adjudicated live by Guinness World Records.

To achieve the record, a sample 4-page category test file from the ISO 24734 standard testing printer speed testing procedure was printed for 500 single-sided, continuous pages. This was done in the fastest color mode on A4 size paper on six different USB-connected devices from the same product class. Tested products included representative laser and inkjet color desktop multifunction printers priced at less than $1,000 USD, and printers priced at less than $800 USD. These devices included the Hewlett-Packard Officejet Pro X551dw Printer with HP PageWide Technology, Hewlett-Packard Officejet Pro X576dw multifunction printer with HP PageWide Technology, LG Machjet LPP6010N inkjet printer, Lexmark OfficeEdge Pro5500 multifunction inkjet printer, Xerox Phaser 6280/N laser printer and Brother HL-4570CDW laser printer.

Printing speed was calculated on "EFTP effective throughput," which is a pages-per-minute score resulting from measurement of time from the initiation of the print job on the host PC until the last page of the job lands in the paper output tray. The printed material was evaluated by Wirth Consulting in terms of the following qualitative measures: color, register, definition, clarity, and the degree to which it resembles the original digital image. The final determination of the image quality was at the sole discretion of Guinness World Records.

The HP Officejet Pro X Series printed 500 color sheets faster than the other printers tested, besting the closest competitor by about two-and-a-half minutes, and able to secure its world record.
