Mapping LPT1 to IP printer: System 66 error

I'm using an old DOS program that gives the option of printing to LPT1, 2 or 3.  My computer is running Windows XP and has no physical LPT ports.  I would like to remap LPT1 to print to an HP LaserJet 4200 printer using HP jetdirect 680n, which is accessed through a Linksys Wireless B router.  The printer is currently being used by two different computers (both Apple and IBM systems), but is not set up as a shared printer on my computer.  I am able to ping the printer using its IP address.  I am using Norton Antivirus 2007.

I understand that remapping can be accomplished using the "net use" command in the DOS window, but I get the error message "System error 66 has occurred.  The network resource type is not correct."  The syntax I used is
net use lpt2 \\mycomputername\printername /Persistent:yes
I've tried the command in various ways using lpt1, 2 and 3, and dropping the persistent command, but still get the same error.  Any suggestions?

Close the lpt1 connection first.

net use lpt1 /delete

After that processes, then try your net use command again.  Your syntax looks fine.

I tried

net use lpt1 /delete

I got the message "The network connection could not be found"
Create it as a shared printer, then do the net use command.  This link gives a good explanation of printing to an IP printer through lpt1:

YES!  IT WORKED!!  Thank you so much!  I am now able to print from my DOS program to my IP printer.
My problems were twofold:  
  1) The printer was not set to be shared, and
  2) I was using the computer description rather than the full computer name in the net use command.

michko pointed me in the right direction, and with a little experimentation with the net command, I finally put the pieces together.
You are very welcome.  This reaction is one of the biggest reasons I enjoy EE so much.  Glad I was able to help.
