SAVE A TREE!

When using the Unix machines in the lab, there are numerous tools you can
employ to use less paper when you print a document.  Here are some
suggestions (including programs described below that you may not know
about):


(A) Don't print it!  Do you really need a hard copy of this document at
all? [OK, having gotten that political manifesto out of the way, here are
some other ideas.]

(B) For PostScript documents: examine with ghostview beforehand. If the
document doesn't show up properly here, it certainly won't print. (The
converse is not necessarily true. Documents that _do_ appear in ghostview
won't always print (e.g., if "showpage" is missing).)  This will, however,
catch errors such as forgetting to remove an email header from a PS file
sent to you by mail.

(C) Use a "duplex" printing queue.
There are at least five printers in the lab, including the big
high-capacity ones (HP and Talaris) that are capable of printing to both
sides of a sheet of paper.  You can use these on a per-time basis by doing
	lpr -P<name_of_printer> <filename>
e.g.,
	lpr -Pduplex2 myfile.ps

Alternatively, you can set a default printer:
	setenv PRINTER duplex2

The printers are:
	duplex1		duplex version of lheaprt1, Rm 34
	duplex2		duplex version of lheaprt2, W230
	duplex3		duplex version of lheaprt3, W230
	duplex4		duplex version of lps202,   Rm S-202	
	groduplx	duplex version of groprt,   Bldg 1, Rm 240

(D) enscript
This package is designed for printing text (not PS or other formatted
documents). With it, you can do two columns, change fonts, print
landscape, and combine these features to print "two-up" (two pages 
side-by-side in landscape).  You can also use the "-P" flag in the same 
fashion as lpr, above, to specify a printer.
Examples:
	enscript -r <filename>		   "r"otate to landscape
	enscript -rfCourier7 <filename>	   landscape, and print in tiny font.
	enscript -2rG -Pduplex2 <filename> two-up, with "gaudy" header

See the enscript manual page for more information.

(E) psf  (the PostScript Filter)
This is a similar package to enscript, in that it is designed for plain
text files. psf allows you to print four-up (small but readable), among
other options.
Example:
	psf -4x <filename>		   four-up, with "X" printed to 
					   visually distinguish the pages. 

There is a man page for psf, but "psf -" will give a quick summary of options.

(F) psmulti
This is a slick package for printing multiple PostScript pages on one
sheet. It can do two, four-, even nine-up (perhaps more?!) !  It prints an
attractive "dropped shadow" on each of these reduced pages.  You can also
specify which pages to print.
Example:
	psmulti -pages 4 <filename>	   four-up of PS document

There is a man page for psmulti.

Hopethis proves helpful.
