I've added a HP 4250 printer to about half a dozen Windows XP PCs in our office without any problems whatsoever, but for some reason I haven't been able to add it to one particular PC today.

I go through the Add Printer wizard to add a local printer attached to the PC, enter the new port number as a Standard TCP/IP Port, install the driver. At the end of the wizard I get the following error message:

Full error message: "windows cannot connect to the printer. either the printer name was typed incorrectly, or the specified printer has lost its connection to the server."

This doesn't make any sense as I am able to ping the printer from the PC. The print spooler is running, and any firewall software on the local PC is switched off.
