NAME
gcan, homespool, gspool - interface to gnot laser-printers
SYNOPSIS
gcan [ option ... ] [ file ... ]
homespool
gspool
DESCRIPTION
This command prints files (standard input by default) on a
gnot laser printer. Troff(1) output and ordinary text are
generally recognized and processed appropriately; in any
case the first option can be used to specify the type of
input:
-sb Bitmap files. (See bitmap(6)).
-sc ordinary text.
-sd troff output.
-sm MIDI output.
-sr `TYPE=rle' run-length-encoded bitmaps.
The destination printer is determined in one of the follow-
ing ways, in decreasing order of precedence:
option -d dest
environment variable `candest'
printer named in file /sys/lib/candest
These options are common to all classes of input:
-- No more options.
-dg Destination is printer outside of graphics lab.
-du Destination is printer in dirty room.
-dt Destination is printer in 2C465 (tom's office).
-p Output goes to /n/bootes/usr/$user/pspool for
proofreading.
-ffile Output goes to file for debugging.
-G Output goes to /usr/$user/spool for local printing.
-H Suppress header page.
-I Do not attempt page reversal (no page number index
is generated).
-ln Set number of lines per page (forces `c' service
even if data look like troff).
-%n Print odd-numbered pages if n=1, even-numbered
pages if n=2.
-D Turn on debugging.
-o... Print only those pages whose numbers appear in the
list (e.g., `-o 1,3,5-8').
GCAN(1) GCAN(1)
-O... Like `-o', except pages are counted sequentially,
i.e., troff-assigned page numbers are ignored.
(Both options have the same effect on non-troff
files.)
These options are only valid with the types of input indi-
cated:
-mn Set magnification to n (type `b').
-sn Set point size to n (type `c').
-xn Move the image n pixels left (types `c', `d', `r').
-yn Move the image n pixels down (types `c', `d', `r').
homespool initializes the files needed for a private
spooler; gspool starts such a spooler. See the -G option.
FILES
/sys/lib/candest name of default printer.
/n/bootes/usr/$user/pspool proofreading spool area.
/n/bootes/usr/$user/spool spool area.

BUGS
More input classes should be divined from the data.
