afaxprt [-pnum] [-n] [-dn]<AFAX_filename>
eg afaxprt -p2 MyFaxFile
If the -p option is not used, all pages are printed.
The -n option does not actually send the data to the printer. Useful with the debug option -d.
Sends the AmigaFax document to the preferences printer. It is a good idea to set your printer for high density. Using a dot-matrix, Halftone Dithering, Integer Scaling, Black and White, Density 7 appears to work ok.
Note that this has not been extensively tested with printers other than the HPLJIII and the Star NX10.
