Spencer Labs specializes in testing printer web page yields, and providing the information necessary to determine price per web page - that is the unit cost of printing: Laser vs. Inkjet, and differing designs within the types of printers. As an independent laboratory, a variety of printer manufacturers utilize them to approximate cost per web page. Spencer labs say, “a important, standard test Document is necessary. Because the yield can vary print-to-print on many printing systems, significant estimation of what amount of prints may be printed from an ink or toner cartridge calls for actual evaluation of representative sample cartridges"
For black colored text, a document is made in certain text dimensions, with specific margins. An innovative new cartridge is place in the printer, as well as the document is printed until the ink works out, or even the cartridge is assessed as vacant by the printer pc software. The resulting copies are counted.
For shade, a document is made with text and company illustrations, such as a cake chart. Although we don’t remember looking over this, I assume the photos use roughly similar level of each color. The document is imprinted until a cartridge is emptied. With many printers using tri-color cartridges, if an individual color is exhausted, the printer generally won't allow additional images. Once again, all pages and posts printed tend to be counted. Black cartridges tend to be ranked for a greater number of pages than colored cartridges, and so the colors would be the very first to operate down. With notably high end printers, as opposed to a tri-color cartridge, you will see specific color cartridges. However, many printers need your emptied shade be replaced before extra copies tend to be imprinted
