Try to turn the printer off and then on again. If that does not clear it you need to re-install the driver, the driver may be corrupt.

1. Turn the printer on.
2. When the memory starts counting on the control panel, press and hold the green SELECT button. Continue to hold green SELECT button until all three Control Panel LED's are illuminated and on solid.
3. Release the green SELECT button.
4. The control panel will display SELECT LANGUAGE.
5. Press the DOWN ARROW button until control panel displays COLD RESET.
6. Press green SELECT button. The printer will perform a cold reset and then continue its power-on sequence.

Get your converters on ebay. If you go to any electronic, computer store you will get hosed.

It is a dip switch setting, on dip switch #6, it needs to be "On" It will then single space the lines. After re-setting the switch under the cover, turn off the printer for 30 seconds to clear the buffer...then holding the "LF" button, turn it back on, until its self test is complete. You problem will be over.
