I am running DIGITAL TCP/IP Services for OpenVMS Alpha Version V4.2 on a
AlphaServer 1200 5/533 4MB running OpenVMS V7.1-1H2 with several print
queues configured and working without trouble.

On the rare occasions when I need to add a print server queue I almost
invaribly run into one odd problem or another. At the moment, I would like
to configure a print server queue to enable printing to a Brother Intellifax
4750e
(http://welcome.solutions.brother.com...C8100HUK_A.pdf)
which is already on the network and accessible to Windows PCs using LPR
Protocol and "BINARY_P1" as the queue name.

I have added an entry to the UCX Hosts database as follows:

xxx.xxx.xxx.xxx ACCT$FAX, acct$fax

SYS$STARTUP:UCX$LPD_STARTUP.COM contains the following:

$ init/queue/start-
/owner=[1,4]-
/retain=error-
/device=server-
/process=ucx$lpd_smb-
/protection=(s:e,g:r,w:w,o:d) ACCT$FAX -
/library=emsdevctl_hplj -
/form=normal/schedule=nosize -
/default=(nofeed,form=normal)

and UCX$PRINTCAP.DAT contains:

ACCT$FAX|acct$fax:\
:lf=/SYS$SPECIFIC/UCX_LPD/ACCT$FAX.LOG:\
:lp=ACCT$FAX:\
:rm=acct$fax:\
:rp=TEXT_P1:\
:sd=/SYS$SPECIFIC/UCX_LPD/ACCT$FAX:\
:cr:

The queue initializes and starts without problem and sending a print command
to the queue gives every indication that it is working normally:

$ pri/que=acct$fax login.com
Job LOGIN (queue ACCT$FAX, entry 859) started on ACCT$FAX
$

Job LOGIN (queue ACCT$FAX, entry 859) completed
$

But, the printer shows no signs of life and nothing prints.

The IP address in the Host entry is correct, UCX$LPD_SPOOL:ACCT$FAX.DIR
exists and has the same Protection as similar folders for working queues
(System:RWE, Owner:RWE, Group:RE, World:RWED).

What am I missing here??
