I came across this topic here in a Google search after my CC4 tray icon occasionally disappears for some reason I can't figure out, and wanted to say the Don G. and timmy2 methods still work in 2022 with my Brother MFC-L2710DW printer. I didn't try the skwire method, but appreciate all the time he put into his solution(s).
My only question is...how are the Don G. and timmy2 methods different? I know one's a batch file and one's a shortcut, but timmy2's method just seems to make the shortcut into a batch file. I don't see the reason for that if the shortcut is sufficient. Just save a copy of the shortcut somewhere safe in case you lose the original one.
If I'm wrong, and I probably am, please straighten me out.
Thanks again for everyone's efforts in this.
