Since you have printer configurations already set up for other applications, try this.
Open OpenOffice Writer, then open a document. Click on File, Printer Setup. If your installation was done correctly, you should see a dialogue box. In that dialogue box, there is a drop-down text-box. Click on the down arrow at the right-hand end, and you should see the already-configured printers. Click on one to select it, then try to print using the selected printer.
