Dan,

Per your request regarding print spooling.

George (gk4)

------

The following options are common between BSD lpr, LPRng, and GNU lpr.

-c = cifplot data filter
-d = tex data filter
-g = plot data filter
-l = binary data - do not filter
-n = ditroff data filter
-p = format with pr
-t = troff data filter
-v = raster image data like Benson Varian filter
-Pprinter - send output to printer
-h = suppress header page
-m mailto - send mail to mailto upon completion of spooling
-s = use symbolic link to file - compatability only on LPRng
-#copies
-1,2,3,4fontname = font for troff font position i
-C class = Class for burst page
-J jobname = job name for burst page
-T title - title for pr
-U username = user name for job
-i cols = indent input by cols columns
-w width = page width

The -1, -2, -3, -4, and -s options are ignored on LPRng and are there for
compatibility only

The differences for CUPS are that the following parameters are accepted but
ignored:
-m mailto
-s
-i
-w
-c
-d
-g
-n
-t
-v
and the -1,-2,-3,-4, and -U options cause an error


So CUPS has in common with the others only:
-l = binary data - do not filter
-p = format with pr
-Pprinter - send output to printer
-h = suppress header page
-s = use symbolic link to file - compatability only on LPRng, CUPS
-#copies
-C class = Class for burst page
-J jobname = job name for burst page
-T title - title for pr


My thanks to Jim McDonough for the above information.

Subject:  lpr subset standard wanted



If possible, I would like to document the subset of lpr functionality
that can be safely used by applications into the LDPS 1.1 portability
guidelines and perhaps the LSB specification as well.

Could someone investigate:

  - CUPS
  - BSD lpr
  - GNU lpr
  - lprng

and find out which options/features are supported by all of them
(and then, which options/features have the same behavior).

If you're interested in this task, please let me know.

A draft would need to be completed in one week if this is to make the
LDPS 1.1 beta.  (The current target for LDPS 1.1 beta is January 25th.)

Thanks Jim.  Given the support for CUPS, my inclination would be to
base any LDPS recommendation for printing on the above (smallest)
subset of lpr functionality.  There are a few options I might miss,
but nothing that applications really need to put on the command line
automatically.

And I would also drop -C and -s from the list and include a strong
recommendation to add options in a dialog box.

Any comments?

I suspect we should leave -m in but document that it might do nothing. Thats
harmless

You need -s to print large files on many setups, and tools do use it knowing
that its a good polite way to do printing. Granted lprng etc dont care but
they ignore it so its ok.

CUPS I suspect is about to become considerably less relevant for the short
term. Nevertheless the options it drops are the bizarre ones like troff
support and I see no reason to disagree with the proposal to not document
stuff that the others have but it lacks.

Klaus Singvogel from Caldera Erlangen has compiled a list of 
different print packages and command line switches.

I dropped -m because it had two incompatible implementations.  One
with an argument (the address) and one without (email the user who
printed the job).
 
I checked in the new draft with a "Printing" section to CVS.  Please
check it out at:

  http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/~checkout~/ldps/ldps.html?rev=1.19&content-type=text/html&cvsroot=freestandards

Does anyone see the need for an additional beta period due to the
addition of the printing section?  I don't see any reason to delay the
official release (no comments were received) of 1.1 or any reason to
leave out the printing section.

Checked out; looks good to me.  I have been trying to get around to
doing this but I see you beat me to it, Dan.  Thanks!

Well, on general principles I wouldn't encourage this kind of last
minute addition (it bit us on ncurses in 1.0).  But in the lpr case
seems to me that we've been over the general contents of the lpr
section a fair bit informally.  There will always be another release
after 1.1...

We at Caldera are happy with the printing proposal

No beta period needed.
