Operation of ADC and MEt
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
already-stored raster graphics data using a variety of compression
techniques. This allows the printing of many raster graphics pages
which would have caused a Memory Out error on previous
HP LaserJet printers having the same amount of memory.
