Printing problem in Musescore 3
OS is Linux Mint Mate 19.2. Previously used Musescore 2 in both Win7 and Mint with good results. Followed advice here and downloaded Musescore 3. Although I had not installed v.3, when opening scores in the v.2 folder, they open in 3 by default, even though v.3 is now in Trash, no other v.3 items anywhere in computer, and package manager shows only v.2 as installed.
Since v.3 download, cannot print scores, as printer dialog box shows v.3 cannot find printer, which works as expected for any other print job requested. Note that the only option shown is Print to file as PDF.
Also another pop-up displays that I have never seen before. I guessed the errors mentioned were the originally shown 0.00 margins, which I changed, but the message persists.
