I have a XP Home, with a local printer connected to same router, with an IP assigned to printer. I am using Remote Desktop Connection to connect via a VPN, to XP Pro and run apps and print from there back to me locally. I can connect to the XP Pro machine and work. I loaded the closest model printer driver on the XP Pro machine and pointed it to the IP of the printer. I can ping the printer IP all day from either side. When I send a test print from the remote end back to the local printer, the LED window will illuminate as if it received a signal, but never prints.
