Sending document to fax printer no longer works in Libre 5

[chpasha]

Hi there,
I have Libreoffice 5.4.1.2 on ubuntu 14.04. Since updating from Version 4 to 5 printing to fax printer (created with spadmin many years ago) stopped working. File /home/user/.config/libreoffice/4/user/psprint/psprint.conf is present and it’s content is following:

[__Global_Printer_Defaults__]
DisableCUPS=false

[Brother Fax]
Printer=SGENPRT/Brother Fax
DefaultPrinter=0
Location=
Comment=
Command=/usr/bin/brpcfax -P BRFAX -o Paper=A4 -o fax-number="(PHONE)" "(TMP)" 
QuickCommand=
Features=fax=
Copies=1
Orientation=Portrait
PSLevel=0
PDFDevice=1
ColorDevice=0
ColorDepth=24
MarginAdjust=0,0,0,0
PerformFontSubstitution=false
SubstFont_Cumberland=Courier
SubstFont_Thorndale=Times
SubstFont_Times New Roman=Times
SubstFont_Timmons=Times
SubstFont_Arial=Helvetica
SubstFont_Courier New=Courier
SubstFont_Albany=Helvetica
SubstFont_Helmet=Helvetica

the command for sending file to the fax is correct - I used it in command line and it does work. In version 4 the input dialog for fax number was coming when sending to the fax, but now even if I put fax number in the command explicitly - nothing happens. I would appreciate any help

found solution myself. so the reason why it doesn’t work anymore - the change in libreoffice 4.3 after which only cups printers are supported. I’ve already had my fax added as cups printer, so the problem was missing dialog where I could put my fax number. To bring it back we have to do all the things mentioned in this ticket
