Hi all - the list comes through again.
My original question is at the end of this summary.
The solution I required turned out to be very simple to implement. All I did
was edit /etc/magic to include the ^D%! "magic number" as a type of
postscript document on the SPARCs hosting the SPARC printers.
Some people suggested the use of a dummy printer entry as a means of adding
a filter. The following is one method suggested by James Dang which can be
adpated to add filters of your choice,
1. Create a dummy printer called "lwsparc" say. You need to create a spool
directory as well e.g. /var/spool/lwsparc
2. The /etc/printcap of the printer server will look something like :
lwsparc|sparcdos|Sparc Laserwriter with dos filter:\
:lp=/dev/null:if=/usr/local/lib/lwsparc.filt:lf=/tmp/lwsparc.log
sparc|Sun Sparcprinter NEWSprint printer:\
:mx#0:sf:sb:\
:lp=/dev/lpvi0:\
:sd=/var/spool/sparc:\
:if=/var/newsprint/lpd/if:\
.
.
.of=/var/newsprint/lpd/of:
3. The script for /usr/local/lib/lwsparc.filt is :
# this filter will strip off CTRL-D created in DOS environment.
sed '1s///1' | /usr/ucb/lpr -Psparc
Somehow you have to actually type in Crtl-D in the substitution of
the "sed" command.
4. "lwsparc" is dummy on unix side, but should be a printing queue on dos side.
A number of people suggested editting the win.ini file
on the PCs to include CntlD=0, I have passed this fix onto our PC people.
Apparently some users were aware of it, some not.

Original Question
Hi all,
can anyone shed some light on this problem I am having with NeWSprint
2.1 and an IPC running 4.1.2.
Some postscript files produced from MS Windows contain Control-D as the
first character. This contrl-D causes the SPARCprinter and NeWSprint to
select the incoming file as an ASCII file, since it has not detected the
%! as the first chars in the postscript file. The PCs producing these files
are running a mix of PC-NFS, Novell and NCSA-telnet, and are on our network.
I wish to filter out the control-D so that these postscript files will
print successfully (instead of the raw postscript).
I have a filter which does the task I want but I cannot incorporate
it into the SPARCprinter's printcap entry. I tried a script that called my
filter, then the standard if filter, but this did not work. I tried defining
a remote printer which had as its if entry the filter I want to use, this
also failed.
I cannot use my filter without causing the lpd_script to fail.
MY QUESTION : Has anyone else solved this problem or added a filter to the
SPARCprinter successfully.
I will summarise.
