a particularly printer friendly version of the same documentation: less paper and ink/toner, or a ready made pdf rendering...

...would be running the plain manual pages through a2ps, a powerful text to PostScript converter which is included in many linux distros or repositories. E.g, running

perldoc perlboot | a2ps -B -=book --printer=your_printer
[download]

on a duplex-capable printer will print the manual in landscape mode, two pages on each sheet, double sided, and with the pages sorted as a booklet: take them from the printer, fold the bunch in the middle, and voilà - you have a compact manual to take with you.

For a single sided printer things get interestingly more difficult; check the a2ps info pages.

update: just saw that JavaFan gave a related answer. The above command would print the 54 page CGI manual on 13 pages.
