 %description
 PPA (Printing Performance Architecture) is a closed, proprietary protocol developed by Hewlett Packard for a short-lived series of DeskJet printers. In essence, the PPA protocol moves the low-level processing of the data to the host computer rather than the printer. This allows for a low-cost (to produce) printer with a small amount of memory and computing power.
