Cannot send fax from LibreOffice

LibreOffice Writer allows me to open my Brother Fax printer BRFAX and enter a fax number. But when I click to send, nothing happens. My AIO printer is Brother MFC-J1170 DW. I installed it on my Linux Zorin 17.3 computer and the regular print and scan functions work. The fax printer BRFAX was automatically installed as part of the package installation. But I cannot get it to work. I would appreciate any assistance I can get.

Version: 25.2.3.2 (X86_64) / LibreOffice Community
Build ID: bbb074479178df812d175f709636b368952c2ce3
CPU threads: 18; OS: Linux 6.8; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US
Flatpak
Calc: threaded

This has been broken for me in one way or another for nearly 20 years, even in OpenOffice. I’ve had at least 3 different printers over that time, and none of them worked from within OpenOffice or LibreOffice using the aio protocol or any other proprietary protocol that was supposed to communicate with the fax engine of the printer. This was either on Linux or macOS, can’t speak for Windows.

more likely not LO specific.
