Operation of ADC and MEt
Image Adapt
The goal of ADC is to automatically and transparently reduce Memory Out errors caused by raster graphics pages. MEt extends this goal to reducing all Memory Out errors and eliminating Print Overrun errors.
During the printing of a page, if available printer memory becomes low, all HP LaserJet 4, 5, and 6 family printers and the HP Color LaserJet printer have the ability to automatically compress any
With ADC or MEt, PCL 5 printers can typically print a full page of raster graphics in base memory without a memory out. This is especially true for line art and typical business graphics. Other types of graphics such as scanned photographs (especially if a technique called
Image Adapt is only used as a last resort for compressing raster graphics data and as such will rarely be seen. It reduces a raster graphic image to
Image Adapt can be disabled on some of the HP LaserJet 4, 5, and 6 family printers if required, but the technique varies. On the HP LaserJet 4, 4M and 4Si the user will have to add more memory to effectively remove the need for Image Adapt. Image Adapt can be disabled on some of the other HP LaserJet 4, 5, and 6 family printers by using a PJL command (refer to the respective printer user manuals for further
