cannot print to cups printer with libreoffice command

Question

i'm using Ubuntu Server 18.04, and i'm trying to execute this command in order to print a xlsx file to a cups shared printer,

sudo libreoffice --pt epson /folder/Planilla.xlsx

but nothing happens, the command never ends and the prompt dont comes back.

I tried with an ods files, and gets the same result. I don't want to export to pdf before print.

any ideas?

Thanks in advance, Martin
