I've done that, which should improve things for users of SMB networked 
printers, as well as avoiding the lockup for users who do not have a 
printer configured on an LPT port.

Edge cases do still exist though. Someone may have a printer configured 
on LPT1, but it is switched off or disconnected. They will still 
experience the lockup. Also printing to IPP networked (and I presume 
other connections that present fake port names, like USB) printer 
results in a file being created in C:/, perhaps we can catch this in 
direct-print-region-function by checking if printer-name starts with 
"IP_" or "USB", and give a warning that the user will need to use an 
external application to print to that printer.

If Dhuvra finishes his helper application, we could configure that as 
the default print application, since it will give the ability to print 
on USB and non-SMB networked printers as well as any printers that do 
not accept plain text over the wire.
