*If* your JetDirect card is of recent ROM revision (or new ;), you can print
simultaneously with any of the supported protocols (well, not really
simultaneously, only one protocol at a time may be active in the card, but as
soon as that transfer finishes, the first protocol to request a connection will
get it).
 
BTW, what are you going to use to print to a JetDirect from HP300's? As far as
I
know, HP has nothing that will talk to a JetDirect in an MPE environment.
 
What we use is Proactive System's Fantasia laser printer formatter, which comes
with the value-added goodie that it can print to a JetDirect using the TCP
HPNPF
proprietary protocol. With Fantasia, we can either print 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).
