[comp.sys.apollo] LPR filter

From Bob Shaw:

	Another question....  
	"What if" ....... someone wanted to use this on Postscript and/or 
	regular ASCII / text files, what would be involved? 
	
	My particular printer is used for almost everything , including
	hpgl, bitmap, postscript, ascii etc.  I am trying to convert 
	everything possible to lpr.

The BSD print server sends all files to the printer EXACTLY as is with the
exception of the changes you make in your filter. I am assuming that you
are sending the file to an Aegis print server using PC in the printcap 
entry; if so, the Apollo print server is determining, based on the file
sent, what Apollo supplied filter to apply to the file to turn it into
the destination type (i.e. Postscript). The problem you will have is that
you will want a banner page ahead of the print job, but in order for the 
apollo print server to print the job correctly, the banner page will HAVE
to be in the same format (hpgl, postscript, ascii, etc) as the original 
print job because the Apollo print server will apply the filter to all of 
the job. So, unless I'm missing something, you will need to determine the
type of file (in your filter) and the append ahead of the file a banner page
of the same format. A difficult task I would believe. 

A Question for any HP reps reading this list...Is there any other way to 
intercept the USER information from the remote system and have that be
the USER NAME printed on the Apollo Print Server Banner Page (without
producing a banner page via BSD printcap filter). Any suggestions would
be appreciated.

Does the Apollo Postscript Print server have an HPGL-->Postscript filter?
	
	I'm curious why you couldn't email "directly" to me.
	
	
I am not sure, but I believe I couldn't respond to you directly because the Apollo
sendmail doesn't support MX mail???

Bob, I hope this helps...
