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.
