I have a NetPrint server which under Ultrix works fine.
In that printcap entry for a filter has something like:
 :if=/usr/dpi/infilter|/usr/dpi/dpifilter sci_NPS 10001:\

Ultrix will take this and run a shell program.  The key
is that the comand line argument to the second program
gives the printserver and port number.  The infilter
gets the regular command line arguments passed to an if filter.

NetBSD lpr does not run a shell so I have to go to some
effort to use printers connected to this print server.
(Maybe someone can show me how to do this better I basicly hacked
 a program which invoked infilter piped the output to dpifilter
 where I had hard coded the command line arguments)

Does LPRng support shell command lines for print filters
like Ultrix does?
