bug#3332: bug#4275: 23.1; Printing

[Francis Wright <f.j.wright@qmul.ac.uk>]

I no longer have access to the printer I referred to in my initial bug report. My current printer is connected using WiFi via the Internet. I tried the recipe described by Arash and got essentially the same result. To be precise, I got this message

w32-direct-print-region-helper: Opening output file: Permission denied, c:/WSD-cdd02b81-88de-4da9-ac0b-52cc3703cc62

I'm running
GNU Emacs 27.2 (build 1, x86_64-w64-mingw32)
 of 2021-03-26
on Windows 10.

So it's still a problem. Thanks for looking into it again.

Francis

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:

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
