All HP LaserJet 4, 5, and 6 family printers also include enhancements to improve the internal storage of raster graphics data.
With MEt, font data can also be compressed. All downloaded bitmap characters and characters scaled from internal or downloaded scalable outlines can be compressed. The amount of memory savings varies with the size of the characters involved (larger is better) but character sizes can typically be cut in half. This allows roughly twice as many fonts to be downloaded or scaled using a
In prior PCL 5 printers, if the page could not be rendered as fast as the laser printed it, a Print Overrun error occurred unless page protection was manually turned on and memory was added to accommodate it. With MEt, the manual setting of Page Protection and the additional memory required to facilitate it is obsolete. MEt automatically assesses the complexity of the page being printed and if too complex turns on a new form of page protection which uses compression to remove the requirement for additional memory.
In rare circumstances MEt’s assessment of the page may prove to be incorrect. For these cases there is some amount of control over this Page Protection process depending upon which
