I have a network printer (OKI C3200n) running on my home network. I can print wirelessly through my two XP laptops, but I am unable to successfully print to this printer using my new laptop which is running Vista (HP Pavilion dv200). I have configured the printer to connect via a local, TCP/IP port and the IP address for the printer is correct. I have the correct printer driver and the printer seems to install correctly. However when I attempt to print a test page I get an error in the printer dialog box. My Vista machine can ping my printer and I am able to connect to the printer's web page via its IP address. I can simply not transmit print data. I have turned off all firewalls and defender to no avail. I also can sucessfully print when connected via USB just not via my network. I have spent hours on the phone with OKI and HP to no avail. I would be grateful to anyone who can assist me. I am completely at a loss here. Thanks in advance!
