       ppmtomitsu - convert a portable pixmap to a Mitsubishi S340-10 file


       ppmtomitsu  [-sharpness  val] [-enlarge val] [-media string] [-copy val] [-dpi300] [-tiny]


       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.

              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.
