Printer Working Group

The Printer Working Group charter is to develop standards that make printers, operating systems and applications work better.

In 1991 a consortium of printer and network manufacturers (Insight Development, Intel, LAN Systems, Lexmark and Texas Instruments) formed the Network Printing Alliance (NPA). Later members included QMS, Kyocera, GENICOM, Okidata, Unisys, Canon, IBM, Kodak, Adaptec, Tektronix, Digital Products, Pennant Systems, Extended Systems and NEC.

In 1993, the NPA was reformed as the Printer Working Group (PWG) and added HP, Compaq, Microsoft, Xerox, Xircom, Farpoint Communications, Zenith, Castelle, Fujitsu, 3M, Cirrus Logic, Amp, National Semiconductor and Ricoh.

In September 1999, the IEEE formalized an alliance with PWG as part of the IEEE Industry Standards and Technology Organization (IEEE-ISTO).

The PWG has supported the development of:

  • IEEE 1284 parallel port specification
  • IEEE 1284.1 TIPSI (Transport Independent Printer Systems Interface)
  • P1394 — printing protocols for IEEE 1394
  • IETF MIBs in the PRINTMIB working group
  • IETF Internet Printing Protocol in the IPP working group

Famous quotes containing the words printer, working and/or group:

    Although then a printer by trade, he listed himself in this early directory as an antiquarian. When he was asked the reason for this he replied that he always thought every town should have at least one antiquarian, and since none appeared for the post, he volunteered.

    What else are we gonna live by if not dreams? We need to believe in something. What would really drive us crazy is to believe this reality we run into every day is all there is. If I don’t believe there’s that happy ending out there—that will-you- marry-me in the sky—I can’t keep working today.
    Jill Robinson (b. 1936)

    Laughing at someone else is an excellent way of learning how to laugh at oneself; and questioning what seem to be the absurd beliefs of another group is a good way of recognizing the potential absurdity of many of one’s own cherished beliefs.
    Gore Vidal (b. 1925)
