.................. Apollo lpd / lpr questions ...........
I am trying to add to our existing print server the
lpr / lpd capability. Basically, I have several machines
(Suns, Decs, Convex etc) that need to print to my
Apollo print server. I am playing with printcap files
and everthing is fine from the other machines.
1. My problem is on the print server itself. I am using the
:pc option in my Apollo printcap file and have been unable
to have the file name print out on the output pages. The
filename is ALWAYS standard_input. The date and page #
is ok.
Banner pages
2. If I use the cols 2 option , and use page #'s , page 1
starts on the banner page and not on the actual output.
3. If I use postscript ( - trans option ) I can't get the
banner page to print the users name or the file name. It
simply prints Daemon and Standard_input.
4. Is any filter source code available that will enable one
to modify etc for customized banner pages and/or to help
solve any of the above questions/problems.
I have never been able to get a bitmap file to print
using the printcap/lpr method, even though the prf
method works fine manually.
I've read the man pages on this but just wondering if there
are any useful books written on this.
I am using a DN4500 and os 10.3 and a TI 2115 omni laser
printer.
Any comments / suggestions will be GREATLY appreciated.
Thanks in advance.....

Bob Shaw Texas Instruments Dallas bshaw@vlsic2.csc.ti.com ---------------------------------------------------------------------------------- We have a postscript printer connected to an Apollo, running the Apollo print services. What you need to do is add the :if=program in the printcap file. The print file will be sent as standard input to the program and the print server will then process whatever you send to standard output. We wrote a shell script as the program and wrote out a postscript banner page (standard out) then sent whatever was standard in using CAT (no path, will pick up std in); all data went to standard out. Also, the :if (input filter) will send as arguments to the program the remote system and remote user name so you will need to parse that for the information you need (I used echo $* to determine the parms). One important note: we are going to change the program to be a C program because we have problems with the cntrl/d's in the Postscript files produced by Wordperfect. Apparentally, the shell is picking up the cntrl/d and sending an EOF to standard output; why it didn't truncate it before CAT processed it is a mystery to me. Also, we sent the file with -banner off since we built the Postscript banner for remote print jobs. Apollo's PRF automatically determines the type of file and processes it through the appropriate filters. Unix's print server sends the data directly to the printer unless you specify a filter (which I assume could determine the file type and take appropriate action). Hope this helps...
