- WROONNNGGGG!  As of 5.5 MPE spooler will talk to JetDirect cards over any
  TCP/IP network.  Yes, you can leave the JetDirect card in the printer and
  share the printer between all systems (including MPE/iX) that can talk any
  of the protocols supported by JetDirect card.

      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      What do you mean with "HPNPF proprietary protocol"? I am part of the
      developer team and we have the MPE spooler ready to talk to JetDirect
      cards - the code has already been submitted to 5.5 builds and some
      customers are already beta-testing it.  We also used the JetDirect
      developers kit UX source, however, I have never come across any
      reference to "HPNPF" protocol.  There's loads of C code in libraries
      and procedures that start with "HPNP...", however, all that is to say
      is an abbreviation for HP Network Printer.  If I'm missing something,
      someone please correct me.
 
      The only protocols we had to work with to make the spooler work well
      were TCP/IP, UDP/IP, SNMP/UDP/IP, Printer Job Language (PJL),  PCL
      and postscript.  (PCL and postscript were least of our worries, since
      those are usually in the setup files or the spoolfile itself).
 
 
: Fantasia-formatted jobs to any JD PCL printer, or we can set up a
: "phantom spool" that Fantasia intercepts and sends jobs as "passthru"
: (semi-raw in a Unix sense) to a JD PCL printer.
 
: On the other hand, if you can get your hands on the hpnpf source code
: (the HP-UX utility that comes in the UX JetAdmin package), you can get
: down and dirty and program Berkeley sockets on MPE to communicate directly
: with the JD card. (The source code comes in many of the versions of HP's UX
: software distributions).
 
Again, what is hpnpf? Are you referencing the JD developers kit?  If not,
please enlighten me.
