The latest lprng ignores this switch and the -s (symlink) switch, but
accepts them now. Too many people were having problems with stupid
programs (including the Oracle database) that made bad requests (and
couldn't be set to do anything else) to the printer subsystem. -r
isn't used because lprng is completely network based. (i.e. even on a
local machine the file will not just be copied from a location on
disk). This is a security feature. -s is similar.
Ahh another note. One fo LPRng's `features' is a much heightened
security over the basic lpr. More informative output from lpq
requests. Easier running modification of the daemon. Better support
for filters.
(I switched a bunch of machines over from different printing systems
lp, lpr based. The users were a little thrown off by the different
output format, but it made dealing with the printers from machine to
machine much easier).
