Print speed is critically important when buying a printer, but how do you compare print speeds when manufacturers measure it in very different ways?
You need a standard. That standard is ISO ppm.
ISO ppm is based on the international standard for measuring print speed. Completed in March 2009, this standard was developed by technical experts and representatives from leading printer manufacturers, including Canon, Epson, HP, Kodak and Lexmark. Under this standard, black and color print speeds are determined in default, single-side mode in accordance with ISO/IEC 24734.
ISO, the International Organization for Standardization, is a global standard-setting body that develops and circulates worldwide standards to help consumers make informed decisions. ISO has developed over 17,500 standards, including the ISO standard for print speed, as described above.
By using ISO ppm, printer manufacturers are able to provide "apples-to-apples" comparisons of actual real-world print speeds that you would experience using the default settings of any given printer.
ISO print speed allows you to compare printers using a "real-world" printing scenario. It measures the "out-of-the-box" (default) speed, and is indicative of real-world print speeds you should expect at home. Much like MPG ratings on new cars, ISO ppm allows you to make an "apples-to-apples" comparison between printers and all-in-ones and different models from different manufacturers.
Q: What are ppm and ipm?
A: "ppm" stands for pages per minute,"ipm" stands for images per minute. Either version can be used to designate ISO print speed.

Q: Why is there a big difference between ISO ppm and max ppm?
A: Max print speed is determined according to each manufacturer's testing and may require special settings. ISO ppm is measured in default mode, so it more accurately reflects real-world speeds.

Q: How does Epson's ISO ppm speed compare to other manufacturers?
A: Epson all-in-ones offer the fastest ISO ppm print speeds in their class. To learn more about why Epson all-in-ones are the world's fastest*, see the WorkForce 610 speed comparison video.
