GCAN(1) GCAN(1) 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. SEE ALSO troff(1). BUGS More input classes should be divined from the data.
