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.
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.

Enlarge by a factor; Default is

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.

Memory-safing, but always slow. The printer will get the
