In the case of host-based printing, the pre-rasterized pages (turned into bitmaps) and print head commands are sent to the printer (see host-based printing).Windows Print Manager and CUPSThe two major printing system are the Windows Print Manager for Windows and the Common Unix Printing System (CUPS) for Linux/Unix and Mac.
