Inkjet Print Speed Methodology
Print Speeds, stated as pages per minute or PPM, reflect measured values based on Brother's particular testing conditions and are for reference only. Actual print speed may vary depending on printing conditions such as computer configuration, operating system, document complexity, printing frequency, connection method, application software and other factors. Print speed testing does not take into account processing time and data transfer time.
1. Maximum Print Speed on Fast Mode
Print speed testing is conducted with the sample pages portrayed below created in Microsoft Word. The printer runs in Draft mode using A4/letter size plain paper. System configuration for testing utilizes a Dell Pentium M, 1.8 GHz, 512 MB RAM Note Book PC running Windows XP Professional with a USB connection to the printer. Print speeds are calculated based on making a continuous printing of the test page with measurement commencing upon the completion of the first page.

* ISO - International Standards Organization
ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards. ISO is a network of the national standards institutes of 159 countries, one member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates the system.
ISO is a non-governmental organization that forms a bridge between the public and private sectors. On the one hand, many of its member institutes are part of the governmental structure of their countries, or are mandated by their government. On the other hand, other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.
Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society.
