 The eCUPS printer port driver provides the "hook up" between the OS/2 Printer Object created from the eCUPS printer driver and the CUPS printer. That is OS/2 knows how to talk to ports that printers are connected to. in this case we are implementing another port to be avialable along side the parallel printer port, the network (lpr) printer port, the serial (RS232) printer port and so on. This driver allow the OS/2 print "engine" to talk to the Cups daemon which it turn talks to the physical printer either over the network or over a USB connection. (note we don't use the OS/2 USB Printer port driver when using a USB attached printer with CUPS - we always use the CUPS port driver and then let the CUPS daemon do the physical IO).
