It took some time before the print speed of laser printers could reach the 50 pages per minute or ppm plateau. Toner technology could not match the rapid advances made on print engine design which therefore explains the lag. The culprit behind this delay is the awfully longer time it takes for toner particles to fuse and bond permanently to paper fibers. So in effect, printer manufacturers had to retard print speed to accommodate the fusing process and allow it to run its normal course while preventing toner from flaking or smearing. However with the development of the EA-HG or the Emulsion Aggregate High Gloss toner by Xerox in the late 90’s, laser printing turned a different route.
