<h2>NAME</h2>
<p style="margin-left:11%; margin-top: 1em">fax2ps −
convert a <small>TIFF</small> facsimile to compressed
™</p>
<a name="SYNOPSIS"></a>
<h2>SYNOPSIS</h2>
<p style="margin-left:11%; margin-top: 1em"><b>fax2ps</b> [
<i>options</i> ] [ <i>file</i>... ]</p>
<a name="DESCRIPTION"></a>
<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><i>fax2ps</i>
reads one or more <small>TIFF</small> facsimile image files
and prints a compressed form of <br>
on the standard output that is suitable for printing.</p>
<p style="margin-left:11%; margin-top: 1em">By default,
each page is scaled to reflect the image dimensions and
resolutions stored in the file. The <b>−x</b> and
<b>−y</b> options can be used to specify the
horizontal and vertical image resolutions (lines/inch),
respectively. If the <b>−S</b> 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 <b>−W</b> and
<b>−H</b> options.</p>
<p style="margin-left:11%; margin-top: 1em">By default
<i>fax2ps</i> generates for all pages in the file. The
<b>−p</b> option can be used to select one or more
pages from a multi-page document.</p>
<p style="margin-left:11%; margin-top: 1em"><i>fax2ps</i>
generates a compressed form of that is optimized for sending
pages of text to a 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 specification of the black drawing operations is
optimized by using a special 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 description, relative to the straightforward imaging
of the page with a <i>image</i> 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
<i>tiff2ps</i>(1).</p>

<a name="DIAGNOSTICS"></a>
<h2>DIAGNOSTICS</h2>
<p style="margin-left:11%; margin-top: 1em">Some messages
about malformed <small>TIFF</small> images come from the
<small>TIFF</small> library.</p>
<p style="margin-left:11%; margin-top: 1em">Various
messages about badly formatted facsimile images may be
generated due to transmission errors in received facsimile.
<i>fax2ps</i> attempts to recover from such data errors by
resynchronizing decoding at the end of the current scanline.
This can result in long horizontal black lines in the
resultant <br>
image.</p>
<a name="NOTES"></a>
<h2>NOTES</h2>
<p style="margin-left:11%; margin-top: 1em">If the
destination printer supports Level II then it is always
faster to just send the encoded bitmap generated by the
<b>tiff2ps</b>(1) program.</p>
<a name="BUGS"></a>
<h2>BUGS</h2>
<p style="margin-left:11%; margin-top: 1em"><i>fax2ps</i>
should probably figure out when it is doing a poor job of
compressing the output and just generate <br>
to image the bitmap raster instead.</p>
