Part of MacFlex 1.5. MacFlex allows "print-to-FAX" capabilities for any Macintosh application, as well as the ability to submit Postscript and TIFF/F files manually for FAXing. FAXes are submitted via a TCP/IP connection to a UNIX server running Sam Leffler's FAX server software, HylaFAX. You select MacFlex in the Chooser and then print your document as usual. When the application you are using is done printing, a dialog will appear which lets you choose a destination and some other options. Fill this in, click 'OK', and the imaging should proceed. Next, in the background, the MacFlex Spooler will take your job and submit it to the server. This happens automatically, so there's no need to launch anything by hand.
