ppmtomitsu - convert a PPM image to a Mitsubishi S340-10 file



[-sharpness val]

[-enlarge val]

[-media string]

[-copy val]





This program is part of Netpbm(1).

ppmtomitsu reads a PPM image 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 can print in 24 bit color. Images of the available sizes take so long to transfer that there is a fast method, employing a lookup table, that ppmtomitsu uses if there are no more than 256 colors in the image. ppmtomitsu tries to position your image at 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 fails. (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 printer's memory; ppmtomitsu doesn't use this function because pamcat etc provide the same functions and let you view the result on-screen, too. The S340-10 is the lowest common denominator printer; for higher resolution printers there is the dpi300 option. The other printers are also capable of higher values for enlarge, etc., but I don't think that is valuable enough to warrant a change in the program.

For proper results, the input maxval must be 255. Use pamdepth to ensure that it is.

Before Netpbm 10.40 (September 2007), all Netpbm PPM programs, including ppmtomitsu, see a PBM image as having maxval 1, so ppmtomitsu does not function properly with PBM input. You can use ppmtoppm together with pamdepth to turn your PBM input into maxval 255 PPM input that ppmtomitsu will use properly.


In addition to the options common to all programs based on libnetpbm (most notably -quiet, see
Common Options
), ppmtomitsu recognizes the following command line options:

"sharpness" designation. Default is to use the current sharpness.

Enlarge by a factor; Default is 1 (no enlarge)

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.

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).

Memory-saving, 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.
