NAME
       pbmtoescp2 - convert a PBM image to a ESC/P2 printer file


SYNOPSIS
       pbmtoescp2

       [-compress=compressionmode] [-resolution=dpi] [pbmfile]

       All options can be abbreviated to their shortest unique prefix.  You may use two hyphens instead of one to des-
       ignate an option.  You may use either white space or equals signs between an option name and its value.


DESCRIPTION
       This program is part of Netpbm(1).

       pbmtoescp2 reads a PBM image as input.  It produces an ESC/P2 raster graphic printer control stream as  output.

        This  program creates an output that is printable on Epson printers that understand the ESC/P2 printer control
       language (e.g. the Stylus models).  For older Epson 9-pin dot matrix printers, which use  the  ESC/P  protocol,
       see pbmtoepson.


OPTIONS
       Input is read from file pbmfile if specified, otherwise from stdin. Output is written to stdout.




       -compress=compressionmode
              This  determines the compression mode that pbmtoescp2 uses in its output.  Valid values for compression-
              mode are 0 and 1.  -compress=0 results in a printer control  stream  with  uncompressed  raster  graphic
              data.   -compress=1  results  in  a  printer control stream with RLE compressed raster graphic data (RLE
              means Run Length Encoding).  The default is -compress=1.



       -resolution=dpi
              This determines the horizontal and the vertical print resolution set  in  the  printer  control  stream.
              Another  way  of looking at it is a declaration of what the resolution of the input image is (PBM images
              don't have inherent resolution).  Valid values for dpi are 180 and 360.  See hints  for more information
              on this.

              The default is -resolution=360.







HINTS
       RLE  compresses  very well bitmaps of line drawings, preferably horizontal oriented contents like texts, sheets
       of music, etc.  However, bitmaps derived from photographs are not ideal for RLE.  In  extreme  cases,  when  no
       byte  repetitions  occur  in the input, the result will be even slightly bigger than the input.  To avoid this,
       use compression mode 0 to switch off RLE.

       Each pixel in the input PBM image becomes one dot in the printed output.  Therefore, you  must  make  sure  the
       width  and height of the input are appropriate for the print resolution you choose and the print area you want.
       E.g. if you print at 180 dpi and want the image to print as 8 inches by 10, you must supply a PBM that is  1440
       pixels wide by 1800 pixels high.  You can adjust the size of the input with pamscale, pamstretch, pbmreduce, or
       pamenlarge.
