Printing to a Tally T8006 colour printer

[G.M. HADLOW]

Hope someone can help on this one?
I have a friend who baught a new G4 iMac 800 which only works in system Ten.
On his network, he has a Tally T8006 colour printer that is not postscript.
We cant find a driver for it and the iMac cant pick it up on the network.
Tally have informed my friend that they have no system Ten Driver.
Is there any third party driver or solution that any one knows about that
could work?
Also Tally says that he must print through classic - but how does one get to
the chooser in classic to set the printer up?
