The RH 6.1 distribution includes efax as a faxtool, with a textual description of how to set up a printer driver for it. This addition to printtool and rhs-printfilters (and even a bit to tetex-dvips's printfilter) makes it possible to use the printtool to enter a FAX, quite similar to the way SMB works. Since I do not intend to repackage everything, I have not touched efax (I assume it runs nicely) and tetex-dvips. It works for me, but a little work is needed to add the stuff to RH 6.2, see CHANGES files for that.
*blush* The faxprint script is created, but not included in the built RPMs! Sorry for such a trivial mistake. You'll manage. or? --- I am working on more extensions to printtool/rhs-printfilters. Working on 2-sided/booklet printing on PCL printers by making the intermediate PCL stage of HP printers explicit and influencable.
Thanks... However, printtool will disappear soon (7.0, probably) - I'll look into porting this to the new way of doing things.
printtool/rhs-printfilters is gone
