problem direct printing odt templates.

Hello there!!

I already installed Dolibarr 7.0.2, create some new series for my invoices, (3 types) and generally configured.
I use Dolibarr under Mageia Linux. php 5.6, maria DB, and cups.
I can print pdf files over cups, even on a windows shared printer, (been using cups-pdf, for testing, and even direct print to usb port)
my problem is, for the odt files, cups show them as printed succsessfully, but none is printed.
I could download the odt file and open/print via libreoffice, but preffer direct print.
any suggestions?
should I configure headless libreoffice for direct print?
should I install, configure something else?

best regards
