@slugger, model number is correct buddy.
i have already tried the 345 driver and other tvs drivers but none prints in correct format.... and yes printer is little old one.
i hav literally gone mad searching drivers for this printer on google & yahoo.
even tried linux drivers just now, but nothing works. WTH!!!

.
when i take printouts from tally 4.5 version, printout are perfect.
but when i take printouts from Microsoft word, or wordpad or any other text editor, some alian characters r printed.
