Windows does that behind your back because DOT4_001 is not a real port, 
so it gets treated as a file name in the default-directory. To print on 
such a printer directly, you will have to share it and configure Emacs 
to use the network share name, or I think there is a way to redirect a 
real port (eg LPT1) to such a USB port.

OK, thanks.

Could Emacs detect that DOT4_001 is not a real port and not use it as the
default? The fact that Emacs picked it up automatically gave me some hope
that it would work.

The Emacs Manual entry for printing on Windows seems to suggest that
connecting a printer to a USB port is "rare", but I doubt that it's possible
to buy a printer that uses any other kind of connection (other than perhaps
wireless). So I think it would be helpful if there were some specific
guidance in the manual along the lines of what you wrote above. The bit
about sharing and redirecting is there (although I haven't managed to get it
to work yet) but there is nothing about USB ports.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Do you still see this problem in recent versions of Emacs/Windows?

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:

--8<---------------cut here---------------start------------->8---

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.

See the node "Windows Printing" in the Emacs manual, which explains
that the default setting of the printer on MS-Windows isn't guaranteed
to work, and provides a few alternative suggestions for setting up the
printer.

I don't think we can do anything with these problems beyond describing
the various tricks of the trade.

I tried that once long time ago and I did that again briefly before I
answered Lars.  None of them worked (which is not a big deal for me).

Understood.

One solution that works for me on any Windows system is to find a lpr
workalike that knows how to print to the system default printer.
There are several such workalikes floating around.

The "net view" method also works in many cases.

Could this command output a message (on Windows) that points the user to
this manual node when you get this error?

Which command? lpr-buffer?

The error comes from very low-level code, but I guess anything's
possible if we want it badly enough.

[Francis Wright]

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
