v 4.1 doesn't speak to printer

I can print from other applications, such as PDF files, but any Libre Writer files, even if saved in RTF, won’t print. How to fix? Thx

Please indicate your operating system, printer model, method of connection (USB, network/CUPS), and the printer language (PostScript or PDF) being used in LO. Also, are you using the LO or system print dialog?
