I have a smart label printer pro from Seiko, trying to install it onto a machine running windows xp pro with sp3 . I installed it on 2 other machines the exact same and it works fine on them. on the one it won't work it tells me that it cannot find a printer on com 1. Is there a setting or a registery edit that might be affecting it. I also tryed the hard drive in a differant machine to make sure it wasn't the motherboard.
