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> <!-- INDENTATION --> <p>By default <i>fax2ps</i> generates PostScript 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> <!-- INDENTATION --> <p><i>fax2ps</i> 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 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 PostScript description, relative to the straightforward imaging of the page with a PostScript <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 <b>tiff2ps</b>(1).</p> </td> </table> <a name="OPTIONS"></a> <h2>OPTIONS</h2> <!-- TABS --> <table width="100%" border=0 rules="none" frame="void" cols="4" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="11%"></td> <td width="11%"> <p><b>−p</b> <i>number</i></p> </td> <td width="76%"> <p>Print only the indicated page.
