Solaris 8 HELP

Hi,I am basically new to the Unix world. On a workstation there are two printers configured on the print manager and one of the printers is on the default. But when we load on a program and want to print something the default printer or an option topick a printer doesnt come up. Can anyone help please, because I want to configure a printer from the print manager and set it as default. I have got a couple of other questions but I want to see if there is a solution for the problem stated above.Thanks
