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 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 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 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).
Various messages about badly formatted facsimile images may be generated due to transmission 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 horizontal black lines in the resultant image.
