Did you try any of the self test labels? When the printer is turned off, press and hold either the PAUSE or CANCEL front panel buttons while you turn the printer on.
If a label prints out, you likely have communications issues (maybe bad printer cable) or possibly printer driver issues (try to download and install the Seagull driver from www.seagullscientific.com)
