NAME
       g3tolj  - converts a Group 3 fax file into a printable HP-
       PCL file

SYNOPSIS
       g3tolj  [-kludge]  [-reversebits]  [-scale N]  [-aspect N]
       [-resolution 75|100|150|300]   [-compress 0|1|2]   [-page-
       length N] [-duplength N] [g3file]

DESCRIPTION
       Reads a Group 3 fax file (raw or digifax) as input. If  no
       filename  is  given,  stdin is used.  Produces a printable
       HP-PCL file as output.

OPTIONS
       -kludge
              Tells g3tolj to skip the first lines for synchroni-
              sation.

       -reversebits
              Tells  g3tolj  to  interpret bits least-significant
              first,  instead  of  the  default  most-significant
              first.   Apparently  some  fax modems do it one way
              and others do it the other way.  If you get a whole
              bunch  of  "invalid  code" messages, try using this
              flag.

       -scale N
              Scale the output to match  the  printer  resolution
              and paper size, the default of 1.40 will do in most
              cases.

       -aspect N
              Scale the output to match  the  printer  resolution
              and paper size, the default of 1.0 will do for high
              resolution faxes, 2.0 will do  for  low  resolution
              faxes.

       -resolution 75|100|150|300
              Selects print resolution. The default is 300.

       -compress 0|1|2
              Selects  compression method for the print output. 0
              = none, 1 = rll, 2 = tiff.  The default is 0.

       -pagelength N
              Defines the pagelength in inches,  the  default  is
              10.95.  After  this length a pagebreak is generated
              and the last part of the previous  page  is  dupli-
              cated on the next page

       -duplength N
              Defines  the  length  in inches that will be dupli-
              cated after a pagebreak, The default is 0.7.

       dation T.4.
