I have a printer (HP Inkjet colour) which is connected to a netgear print server. However, when I print I get this code "INPAIPO,0,127,127SCO,75,0,75,OWU1" print in the top left hand corner.
Does this happen when it's not connected to the print server? Check in the printers and faxes window of the Control Panel, and in the properties for your computer check for a setting that would have the printer do this. Possibly a network location setting or something...
