I can't print anything from 6.0

I’m on W10 1909 now. May be worth of updating it to the 2004 version and see what happens then. I don’t know why it behaves like I told, but this is how it looks on my computer. I’ve checked everything and found an answer for my question asked here. I’m on the latest printer driver. I won’t reinstall any printer driver, because, no other software with print function available haven’t had any problem with printing. Everything has worked perfectly since September 2018 when I formatted and installed this almost daily using system today. Developers of LibreOffice should look at this and try to fix it. Where can I inform them about it?

Could you save that file as a Word 360 or 365 I don’t remember which exists document and then open it and try to print with this file format? I’m actually not using .odt but always save all as a Word file.

I created the same document in Word 2010 (latest version I have) saved as Teståäö-2.docx, opened it in Writer and it printed no problem. Created again in LO saved as Teståäö-3LO.docx, closed LO, opened it in Writer still prints OK. NB different PC Windows 10 (1909) as I have only one copy of MS Office

I checked my basic fonts in Tools > Options > LibreOffice Writer > Basic Fonts (Western) = Liberation Serif & Liberation Sans, Basic Fonts(CTL) = Arial Unicode MS

I’m updating to 2004 now. I don’t think it help to solve this issue, but at least now I know what’s the issue is.

Not sure this is an answer or not.

This is still happening with lubuntu 2020.04.

Libre Office worked fine on Lubuntu up until several days ago. But I haven’t been using it much. The reason is kind of obscure.

I recently converted from Ubuntu 20.04 with a single desktop to Lubuntu with four.

That’s the setup. No other changes to Libre Office other than the lubuntu install.

This afternoon, I started a new document tried to print it. No luck. Correct Preview, but just Blank pages on the printer.
No changes to printer settings helped.

If all else fails, reboot. so I rebooted.

Still happening on both writer and calc… but I also found I was working on desktop 4. Switching to desktop 1 showed about 10 open Libre Office documents. Not sure why, but closing those resulted in being able to print in the original document.

What may have happened: Emphasis on May.

I opened a new document to edit on desktop 1, and switched to desktop 4 accidentally. so I opened another.
It wouldn’t print. Not sure why. I’m unable to reproduce this condition.
Also noted that the close group in lubuntu does not work to close all open windows for libre office.

Further tries to reproduce should leave Libre Office documents open and try the shutdown and reboot. Something is being held onto in Libre Office across a reboot or possibly with multiple open documents with one or more in a particular state, and it’s killing printing, possibly by proceeding to print not the document displayed in the preview, but another document that just happens to be empty.

Strategy if I encounter this again:

Make sure all open Libre Office documents are closed
Reopen the one I want to print and try it.
If that fails, see if moving the Libre Office config files to an archive location
helps.
