Samba is not letting it access the printer.  The laptop is within the 
corporate domain of my employer.  You can't sign on otherwise.  It's not 
in Samba's workgroup, which seems to be assumed by many of the docs I've 
read.  (In a catastrophically comic attempt to do this, I tried changing 
the laptop's Network identification to use the Samba workgroup.  Not 
only didn't this work, but I couldn't change it back, and once I was 
logged off, couldn't log back on.  I had to get the work IT guys to 
reconfigure it back to the corporate domain.)

I see only the corporate network when I do this.  It is empty, unless I 
enter the corporate VPN, at which point I see all the computers in the 
corporate network that I would see if at work but not my local workgroup.

I have sufficient privileges for installing the driver.  In fact, I have 
gotten as far as installing this as a printer on the laptop.

Yes.  I type in the ip address and I see the printer and all the other 
Samba shares.  Doubleclicking on the printer I get
"Access Denied, Unable to Connect" in the window title bar for the 
printer.  Windows will let me "print" to it, but nothing happens.

This "succeeds" but again, no printing happens.

What I didn't say before was that at one time this worked.  I was able 
to print through this same connection.   Two events intervened:
1.  There was a glitch in the wireless router and I had to reset it to 
factory settings and reconfigure, which I believe I did successfully.
2.  I updated my samba rpm from 2.2.7a-7.9.0 to 2.2.7a-8.9.0

One or both of these things may have messed with the config.

 From all the above, it seems to me that Windows is letting me out to 
see the printer, even connect a driver to it.  But something in Samba is 
preventing me from accessing, and after looking all up and down the 
smb.conf, I don't see it.

smb.conf:

$ cat smb.conf
