Generally, the default printer for a host is the public printer
(prbx301, smith2097) nearest that host.  On unix, the user can set his
own default printer with the PRINTER environment variable -- e.g., the
command

	setenv PRINTER prb2020

would cause lpr to spool your files to printer 'prb2020' by default.
All defaults may be overridden on the command line.  With lpr, the -P
option specifies the printer:

	lpr -Pprbx301 abstract.ps

would spool the file abstract.ps to prbx301.

DOUBLE-SIDED PRINTING

Duplex (double-sided) printing is available on many printers,
including all the ones at the top of this document.  We try to create
a duplex instance for each printer that supports it, which may be used
as the name of the printer:

        lpr -Pprbm2050/duplex abstract.ps

If no duplex instance exists for the printer, you may specify the
option yourself:

       lpr -Pprb1199 -o sides=two-sided-long-edge abstract.ps

Tumble printing (two-sided printing, rotated around the short edge of
the page instead of the long edge of the page) is also an option:

       lpr -Pprb1199 -o sides=two-sided-short-edge abstract.ps

FILE FORMATS

Our printing system supports direct printing, using lp or lpr, of many
file formats, including text, PostScript (PS), Portable Document
Format (PDF), GIF, JPEG and TIFF files.  In other words, you may type

	lpr foo.gif

to print a GIF image, without using a filter.  Note that the PDF
filter is not always perfect, and sometimes you may have better
results if you print the file from inside Acrobat instead.

For image formats (GIF, JPEG or TIFF files), the scaling option can be
used to specify a percentage of the printable page to scale the image
to.  E.g., 

        lpr -o scaling=100 foo.gif

will make the image fit the page.

DOCUMENTATION

Many more options are available.  Use a web browser to read

the CUPS Software Users Manual for current, complete documentation.

THE PRINT QUEUE

The commands 'lpq' or 'lpstat' may be used to examine the print
queue.  

	lpq -Pprbx301c

or 

	lpstat -p prbx301c

will show the queue for prbx301c.  'lpstat -o' will show all current
jobs.  'lpstat -p' will list all available printers and instances.
