Testing of print devices is to be done in a semi-continuous mode at rated speed. It was noted that this type of testing procedure may not be typical of some common usage patterns for print devices, as in office settings for instance. Quote "the yield experienced by a given user may vary significantly from the yield measured by this test method".
Set-off is measured at two different time intervals, 0.35s and 3s. A freshly printed surface is pressed against a paper after 0.35s and after 3s. Then the set-off density is measured. The idea behind selecting these two timings is to know what will be the set-off when the materials are used in a high-speed press and a low-speed press.
ISO/IEC 19752 Information technology — Method for the determination of toner cartridge yield for monochromatic electrophotographic printers and multi-function devices that contain printer components is an ISO/IEC standard method for the determination of toner cartridge yield for monochrome laser printers, introduced in June 2004 and updated ...
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
During the carriage return period, characters were buffered for subsequent printing at full speed during a catch-up period. The two-tone buzz produced by 60-character-per-second catch-up printing followed by 30-character-per-second ordinary printing was a distinctive feature of the LA36, quickly copied by many other manufacturers well into the ...

The printing press check is a step in the printing process. It takes place after a printing press is set up but before the print run is underway. Herzliya Airport (Israel) Runway location and Traffic Pattern chart (left) was erroneously printed as a result of "black layer" 180° misplacement.
