That's not necessarry at all.
You can receive and read faxes without printing them.
Until April of 2019 I was running an old BBS with a ZyXEL Elite 2864L V34
Class 2 Fax modem. Unluckily both serial ports died of that machine ;-(.
I am now UniCorn BBS running at a Pi 1B with only !ROSBink 1.30.

The software was/is FrontDoor 2.02nc, RemoteAccess 1.11 and ZFax 2.23 and more.
The difference between a Modem Call and a Fax Call was detected by the modem,
giving another connect string. FrontDoor detected that by giving a different
ErrorLevel on with my UniCorn.BAT file at the Dos 5 machine served the ZFax
program to receive the fax correctly. After that a message to the sysop was
given. After reading it by the ZFax program I could export it to a graphics
file in the *.PCX format and print that at my Acorn RiscPC if wished to do so.

If ErrorLevel 109 Goto Fax
:Fax

Under M$ Dos there is als BGFax for other (not ZyXEL) modems.

For outgoing faxes I used my ordinary RISC OS DTP program Impression
Publischer+, ArcFax printerdriver and the application !ArcFax in combination
with a E-Tech Bullet E56RVP+ V34 Fax Class 2 momdem at V21ch2, V27Ter, V29
and V17.
Fax uses the very robust Group3 Tonal T30 Modified Huffman protcool for data
encoding at Synchone HDLC HalfDuplex modem speeds, with was very popular at
bad quality phone lines, expecially in the third world, i.e. Africa, India,
South America etc. That's why Fax was used for a very long time world wide.

The last one was received a long time ago, the last one sent the same ;-).
But it is still possible here.

Greetings from Henri.
