Unfortunately I get 

    C:\mydir\getPrn.vbs(22, 1) (null): 0x80041017

on the line 

    For Each objPrinter in colInstalledPrinters

I have a default printer, of course.

Incidentally, Visual Basic Mode constantly gives me
Invalid regexp: "Invalid regular expression"
errors, when I simply try to hit the Enter key. I believe this is a
font-lock problem. Clues will be appreciated.

Looks like my alpha release needs some cleaning up.  Save the following cod=
e
as
getPrn.vbs, then run it with `cscript getPrn.vbs`
First, it should return your *default* printer port
Next, it dumps all the *generally* useful printer info I could find.
Is it fair to say that
   letter, legal, a1, b1
cover all the *common* paper sizes, that Emacs should support?

Let me know, if this new vbs script works. Perhaps I should post the update=
d
code on EmacsWiki, instead of gnu.emacs.sources.
