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 designate 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 con-
       trol 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 compressionmode 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 Encod-
	      ing).  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  resolu-
	      tion of the input image is (PBM images don't have inherent resolution).  Valid val-
	      ues for dpi are 180 and 360.  See hints <#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.

       pbmtoescp2 was added to Netpbm in Release 10.18 (August 2003); it was created  around  the
       same time.
