BEWARE OF DOUBLE STANDARDS!
Ask for ISO Printing Speed.
In order to compare the print and copy speeds of inkjet and multi-function printers, it’s necessary to have a set of uniform standards. Unless identical standards are used it is impossible to know the speed of one printer relative to another – In other words, to know which printer is faster.
It would be like comparing the speed of two runners, one of whom races on a level field and the other up a flight of stairs. Because the testing standards are different, the results cannot be compared and are therefore meaningless.
As a result, Canon and the other leading inkjet printer manufacturers have worked closely with the International Organization for Standardization (ISO) to develop standardized testing methodologies for determining print and copy speeds.
This standard is for digital printing devices – including inkjet printers and applies to both monochrome and colour printers capable of printing on A4/8.5x11” paper. It defines the methodology for comparing plain-paper productivity in default mode using a variety of applications – such as Word, Excel and PDF.
ISO/IEC 24734 designates test files, test setup procedures, test runtime procedures, as well as the reporting requirements for digital printing productivity measurements. The test-system environment, operating modes and job mix are identical for each machine being tested.
This standard provides a methodology for measuring digital copy and is applicable to digital copying devices and multi-function devise with an automatic document feeder. It is intended for both monochrome and colour digital copying devices.
ISO/IEC 24735 designates the test files, test setup procedures, test runtime procedures, as well as the reporting requirements for digital copying productivity measurements. The test-system environment, operating modes and job mix are identical for each machine being tested.
Although both “images per minute” (ipm) and “pages per minute” (ppm) are approved for use with the ISO standards, there is a serious concern that using “ppm” will create confusion. Since the “ppm” unit of measurement can be applied to both ISO standards as well as the previous standards used by individual printer manufacturers, Canon will use only “ipm” when expressing print and copy speeds. Thus, consumers will always know the true speed of Canon Inkjet printers and All-in-Ones.
