I started using LibreCAD about 2 months ago and have had no problems printing.
Yesterday, I printed a project with no problem, and then tried to print a different project and it wouldn't print. This is a project that I have printed many times in the past, but now I can't get LibreCAD to print anything. Even the project I printed earlier. I have tried to print 4 different files and none will print, but I can print from other apps on my computer with no problem.
I have tried using the File>Print option and the toolbar print icon. When I print, it says "printing complete" in the bottom left corner of the window, but nothing is sent to the printer queue.
I can use export as pdf as a work around, but I don't know what changed all of a sudden.
I am running LibreCAD 2.1.3, on Mac OS 11.1 Big Sur, and have printed using Big Sur before with no problem. I have not changed anything that I know of.
I have uninstalled and reinstalled LibreCAD and I have restarted my computer several times.
I don't know anything about MacOS. In Windows I have experienced it happens somehow that in the Windows printer driver box "Print to file" is ticked. It doesn't print then, or somewhere into nirvana. I suspect this happens when you accidentally have tried to print to a printer which is offline. If you take out the tick all is fine again. Maybe it's something similar in MacOS.
