RISCWT: network printer


WWQ&A Question: 


Customer is using "lp -n5" to print and gets 5 copies
to a local queue, but only 1 to a remote queue.

The flags that get sent to a remote printer depend on
the statfilter for the remote queue and possibly the
rembak -X flag.

You did not say what the remote server was:  AIX, SUN, Print
server, etc.

Here is what I see:

AIX Client  -->  Remote Server  (running lpd)

1.  If the remote server is AIX, the "lp -n5 -d\ \
    should work with no problems.
2.  If the remote server is not AIX, then this may or may not work.
    The key is in the "s_statfilter = /usr/lib/lpd/aixshort"
    If this is set, then AIX passes "enq" flags in the control
    file sent to the remote system.

If you have access to a web browser inside of IBM see: 

The control file can be seen by using an iptrace.  When aixshort
is set as the s_statfilter, then the control file looks like this:
The filters at the top (Haix4prt, Proot, ..) that are separated by
a linefeed (0a in center column shows as period in right column)
are flags that are defined by the LPD standard in rfc1179.  The
flags in the center starting with "-o" are "qprt formatting flags"
also called "other flags".  These are ONLY sent if aixshort is
the filter, or rembak has the -X flag.  They will not be interpreted
properly by NON-AIX lpd's.  Finilly the flags at the bottom are the
"enq flags".  These are the valid AIX flags for "enq" as shown from
a "man enq".  These flags are only sent with "aixshort".  Notice the
-N1 flag.  This indicates that there will be one copy.  If you send
from one AIX system to another this should be -N4 for four copies.
This will not mean anything to another system.

If you use the "bsdshort" filter, then the "LPD Standard" part of the
file will contain "four" copies of the filename "dfA466aix4prt".
This should work for NON-AIX LPD's, but is dependent on the lpd

For testing I did this:
\# iptrace -p 515 -a -b -s aix4prt -d tesch flag.trace
 lp -n5 -dtesch aaaa.test 
 vi /etc/qconfig and change the aixshort and aixlong to bsdshort
    and bsdlong
 lpstat -vloclqueue - to redigest the /etc/qconfig file
  lp -n5 -dtesch aaaa.test 
  ps -ef | grep iptra
  kill \
  ipreport flag.trace >

This should give you enough to figure out the problem.  With an AIX
server, these both printed 5 copies.
