I see this problem: I did 'M-x view-hello-file RET' and from the menu
bar, I did 'File->Print->Print buffer', said YES when asked to use the
default printer, and this is the backtrace:

Debugger entered--Lisp error: (permission-denied "Opening output file" "Permission denied" "c:/WSD-5bc23311-7bc5-46f6-a594-1552b4df353d")

I have a HP Laserjet on network connected via WSD Port (hence the name
WSD-5bc...).  This is Emacs 29.0.50 (3ca32105d2) on Win10.

Best, Arash
