doc/emacs/msdog.texi question

[Glenn Morris]

Question prompted by doc/emacs/msdog.texi:

   Emacs on Windows automatically determines your default printer and
   sets the variable @code{printer-name} to that printer's name.

Is that correct?  It looks to me like there is a default-printer-name
function that gets used as a fallback if printer-name is nil.

Yes.  Although this determination does not always succeed in practice.

That function _is_ where we determine the default printer.

I'm confused. Where is the code that does

(setq printer-name ...)

or equivalent? All I see is direct-print-region-function, calling
(default-printer-name) if printer-name is nil.

(And why doesn't the doc of printer-name say "On MS Windows, this is set
automatically."...)

Ah, I misunderstood your question (the sentence you cited states 2
facts, and I thought you were asking about the first one).  Yes you
are right: the part about setting printer-name to the default printer
is wrong and should be deleted from the manual.
