Remote print queue over UUCP

Question:

needs assistance on setting up "UUCP"

Response:

Env:
        AIX 3.2.5
        Spooler/UUCP

Desc:
        Customer has two systems, aix and sco. Unsure if running
        uucp on either one. Customer normally dials from sco
        to the aix systems. On aix, customer has applications
        in which users on sco usually run while connected.

        What customer is looking for is to implement 'remote'
        printing. In other words, submit a job in aix which
        will then be xferred to sco and print.

        Customer notices that for remote queues need to have
        an IP address. Customer does not have any network
        link, only uucp (unsure about that too.)

Act:
        To write a specific backend for remote printing over
        uucp will be only pursued under a consultline item.
        Customer understands.


The /etc/qconfig file would look like this:

lpremote:
        device=remoted
remoted:
        backend=/tmp/uucpq \

Then use a custom backend as described below.

Response:

ACT:
        Did some testing on this and you can use the syntax:

        uux "remote!/usr/bin/enq -c -Pqueue local!/some/file"

        This will print my /some/file on my "local" system to
        the specified print "queue" on the system named "remote"

        This guarantees that the file will be transferred over
        before the attempt to print it is made and without need
        for the shell script above.  

        This could be incorporated into a backend so that when
        jobs are queued to a local queue the above command is
        invoked.  This way, it would appear as a local queue to
        users.

Response:

Action:  I made some modifications to the above script and got it to
   work in the lab.  I'll fax this to the customer.  NOTE:  I'm
   sending this to you as is, and make no gaurentees that it will
   work.  
\#!/bin/ksh
exec 1>/dev/null
hostname=$1
shift
trap "trap 15;kill -15 0;exit 0" 15
/usr/bin/cat $*  > /tmp/uucp.out
uucp /tmp/uucp.out $hostname!/tmp/uucp.out
uux $hostname!lpr -P3930pcl /tmp/uucp.out
if [ "$?" -ne 0 ]
then
 exit 64
fi

Add a local queue, filling in Name of queue to Add, Name of Queue Device
to add, and the backend program pathnaem equal to the full path of your
script.

Action:
Customer is unable to execute the uux portion of the shell script.  I
had him issue it from the Aix command line, and it dialed , connected,
but never did print on the other system.  This HAS to work in order for
us to persue your qdaemon problems.  Customer will try to get this 
portion of this working, and give me a call when you do.

Desc: We made the following changes to the colon file.
Action:  I explained the changes in the colon file

        _d=p   pass through mode
        mo=/etc/uucp/[shell script] hostname   change the pipeline to
                                                execute this command.
