NAME
ppmtomitsu - convert a portable pixmap to a Mitsubishi S340-10 file
SYNOPSIS
ppmtomitsu [-sharpness val] [-enlarge val] [-media string] [-copy val]
[-dpi300] [-tiny] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input and converts it into a format suitable
to be printed by a Mitsubishi S340-10 printer, or any other Mitsubishi
color sublimation printer.
The Mitsubishi S340-10 Color Sublimation printer supports 24bit color.
Images of the available sizes take so long to transfer that there is a
fast method, employing a lookuptable, that ppmtomitsu will use if there
is a maximum of 256 colors in the pixmap. ppmtomitsu will try to
position your image to the center of the paper, and will rotate your
image for you if xsize is larger than ysize. If your image is larger
than the media allows, ppmtomitsu will quit with an error message. (We
decided that the media were too expensive to have careless users
produce misprints.) Once data transmission has started, the job can’t
be stopped in a sane way without resetting the printer. The printer
understands putting together images in the printers memory; ppmtomitsu
doesn’t utilize this as pnmcat etc provide the same functionality and
let you view the result on-screen, too. The S340-10 is the lowest
common denominator printer; for higher resolution printers there’s the
dpi300 option. The other printers also support higher values for
enlarge eg, but I don’t think that’s essential enough to warrant a
change in the program.
-sharpness 1-4
’sharpness’ designation. Default is to use the current
sharpness.
-enlarge 1-3
Enlarge by a factor; Default is 1 (no enlarge)
-media A, A4, AS, A4S
Designate the media you’re using. Default is 1184 x 1350, which
will fit on any media. A is 1216 x 1350, A4 is 1184 x 1452, AS
is 1216 x 1650 and A4S is 1184 x 1754. A warning: If you specify
a different media than the printer currently has, the printer
will wait until you put in the correct media or switch it off.
-copy 1-9
The number of copies to produce. Default is 1.
-dpi300
Double the number of allowed pixels for a S3600-30 Printer in
S340-10 compatibility mode. (The S3600-30 has 300 dpi).
-tiny Memory-safing, but always slow. The printer will get the data
line-by-line in 24bit. It’s probably a good idea to use this if
your machine starts paging a lot without this option.
