Printing greeks on LQ-2180 from HP-UX

[csyrmas]

Hi,
I have an Epson LQ-2180 printer which it is connected to D270 HP-UX system ver.10.20.We use a serial interface to connect printer with HP-UX.When i send to the printer a job which contains greek characters it prints symbols and anything else except greeks.

I was trying through the printer panel to change some settings on printer setup but everything i tried (emulation, character sets, e.t.c.) failed.

From other printers, we use for the same purpose, i find that they use a character set called ELOT928.This character set it doesn't exist on epson.

Has anybody any idea how can i do this thing to print greeks?
This printer (epson LQ-2180) is compatible with HP-UX 10.20 system i have?
ELOT928 character set is compatible with another character set which lq-2180 use?

Thanx
