       fax2ps - convert a TIFF facsimile to compressed POSTSCRIPTtm

       fax2ps [ options ] [ file...  ]

       fax2ps  reads one or more TIFF facsimile image files and prints a compressed form of POST-
       SCRIPT on the standard output that is suitable for printing.

       By default, each page is scaled to reflect the image dimensions and resolutions stored  in
       the  file.  The -x and -y options can be used to specify the horizontal and vertical image
       resolutions (lines/inch), respectively.	If the -S  option  is  specified,  each  page  is
       scaled  to  fill  an output page.  The default output page is 8.5 by 11 inches.	Alternate
       page dimensions can be specified in inches with the -W and -H options.

       By default fax2ps generates POSTSCRIPT for all pages in the file.  The -p  option  can  be
       used to select one or more pages from a multi-page document.

       fax2ps  generates  a  compressed form of POSTSCRIPT that is optimized for sending pages of
       text to a POSTSCRIPT printer attached to a host through a low-speed link (such as a serial
       line).	Each  output  page  is filled with white and then only the black areas are drawn.
       The POSTSCRIPT specification of the black drawing operations is optimized by using a  spe-
       cial  font that encodes the move-draw operations required to fill the black regions on the
       page.  This compression scheme typically results in  a  substantially  reduced  POSTSCRIPT
       description,  relative  to the straightforward imaging of the page with a POSTSCRIPT image
       operator.  This algorithm can, however, be ineffective for continuous-tone  and	white-on-
       black  images.  For these images, it sometimes is more efficient to send the raster bitmap
       image directly; see tiff2ps(1).

       -p number Print only the indicated page.  Multiple pages may be printed by specifying this
		 option more than once.

       -x resolution
		 Use  resolution  as  the horizontal resolution, in dots/inch, of the image data.
		 By default this value is taken from the file.

       -y resolution
		 Use resolution as the vertical resolution, in lines/inch, of the image data.  By
		 default this value is taken from the file.

       -S	 Scale	each  page  of image data to fill the output page dimensions.  By default
		 images are presented according to the dimension information recorded in the TIFF

       -W width  Use  width  as the width, in inches, of the output page.  The default page width
		 is 8.5 inches.

       -H height Use height as the height, in inches, of  the  output  page.   The  default  page
		 height is 11 inches.

       Some messages about malformed TIFF images come from the TIFF library.

       Various	messages about badly formatted facsimile images may be generated due to transmis-
       sion errors in received facsimile.  fax2ps attempts to recover from such  data  errors  by
       resynchronizing decoding at the end of the current scanline.  This can result in long hor-
       izontal black lines in the resultant POSTSCRIPT image.

       If the destination printer supports POSTSCRIPT Level II then it is always faster  to  just
       send the encoded bitmap generated by the tiff2ps(1) program.

       fax2ps  should  probably  figure out when it is doing a poor job of compressing the output
       and just generate POSTSCRIPT to image the bitmap raster instead.
