I agree; the arguments passed to scripts by lpr/lpd are lacking.
Having written scripts which attempt to print useful info in the borders,
this qualifies me to say that the user should not have to do any magick
with pr (manually) before passing it to lpr.
It seems faulty to me that you can do stuff by running "pr file | lpr"
that you could not do in a filter. After all, the idea of a filter is
to do that stuff for us!
All other arguments aside, I had to put my sqprint program as a CIF filter.
Imagine the suprise when someone actually tries to use it on a CIF file.
If anyone writes something to replace lpr, maybe you might look at having
some kind of auto-identification via file(1) for those who are too lazy
to specify which filter to use on the command line? (would be very cool)
