Many digital printing devices may produce the first page at a different rate than their nominal speed due to various factors. These include but are not limited to host computer, driver, application, operating system, type of connection to the printer (USB, Ethernet, wireless), and delay time since the last print. In addition, job characteristics such as black-and-white vs. color, the number of pages to be printed, single-sided or double-sided output, quality setting, number of copies, paper type and size, document content, and document complexity can affect first page out time.
ISO/IEC 17629 specifies a method for measuring the first print out time (FPOT) on plain paper in default mode. It is applicable to black-and-white and color devices, and to single-function and multi-function devices, regardless of print technology (e.g. inkjet, laser, etc).
ISO/IEC 17629 allows manufacturers of digital printing devices to measure the productivity of different digital printing devices with a standard measurement method.
