The Question is:
I've connected a HP laserprinter using UCX (UCX$TELNETSYM). When I give a print
command, I standard get duplicate pages on the same printer. How can I fix this?

The Answer is :
IP port 9100 is used for the LPD server within various HP printers,
while the telnet port is more commonly port 23. The OpenVMS Wizard
is not sufficiently familiar with HP printers to know whether or
not the printer will automatically recognize the incoming protocol
regardless of the port, or if the protocol is assumed based on the
IP port. Please contact HP for details on the implementation of
this particular HP printer.
TCP/IP Services Versions prior to V5.0 are inappropriate on this
OpenVMS Alpha release, and use of V5.1 (or later, as available)
with ECO (as available) is recommended. Use of TCP/IP Services
versions prior to V5.0A (with ECO) is discouraged.
The OpenVMS Wizard is unfamiliar with any previous reports of
doubled print jobs, and would assume that the queue is somehow
configured to resubmit the job, or that the printer is somehow
providing a duplicate. Check for DCL symbols that match PRINT,
check the printcap file for the printer, and check the print
queue definition. Also determine if the job is somehow being
requeued to the printer (possibly due to a communucations error?).
And, of course, check the telnet print symbiont log file. And
check the IP port.
Please also ensure that this particular (unspecified) HP printer
has the correct firmware revision. Some HP printers are known
to have available and/or known to require firmware upgrades.
For general information on IP printing, please see topic (1020)
and other topics referenced there. Topic (1020) also has
pointers to topics containing common IP port assignments for
various IP printers. For information on HP printers, please
contact HP.
