Printer Configuration

Hi everybody,

I hv a problem configuring my printer in QNX6.2.1 machine.

The printer HP LaserJet 4V printer appears in the print selection window
as soon as it is connected to the QNX6.2.1 machine.
But, nothing gets printed on it.

When the same is done with an Epson printer, in the print selection, the
Epson name does not appear.

How can I configure the printer?
If any suggestions, pl. u r welcome.
