Re: [hylafax-users] hfaxd pdf2fax image quality

It depends on your printer driver (which may automatically be
dithering/halftoning) and how good the scanner in your FAX is -- it may be
interpolating.

So, your options are to halftone the PDF first, or fool around with the
rendering options of Ghostscript.
