That appears to be a thermal printer. Why not just ask the TVS company if the printer supports bold font? The contact number is right on their website.

Trying to identify this model, is it this one?:

Looks like a thermal printer to me too (see spec above), which is how it works rather than what operating system it uses.

I see your spec is Windows 7. If you are using it in DOS have you got that operating installed somehow or are you using Win 7 Command Prompt?

Always pop back and let us know the outcome - thanks

OK, so we are getting closer. That printer has drivers for Windows XP, Vista, 7, 8. It doesn't seem to call it a DOS printer anywhere.

1. Does it work OK in Windows?
2. Is it only in what you are calling DOS that you get these odd characters?
3. If you are using it in DOS do you mean Command Prompt because Windows 7 contains no separate DOS.

Can you do a screen shot of these odd ball characters or try to better describe what you see and what you expect to see. Your original post is too vague for us to understand properly.

EDIT:
That is a Dot Matrix printer. Is it possible that where you are saying DOS (Disk Operating System) you really mean DOT?

Always pop back and let us know the outcome - thanks

yes it is dot matrix printer.

my problem is when i give coding for bold,condensed etc., such as chr(14) ,chr(18)

the output is not bold. but instead it shows some small marks or symbols.

"IS THE chr CODING NOT EXECUTE WHEN WE CONNECT DOT MATRIX PRINTER THROUGH USB PORT?"

By "chr" do you mean numerical keyboard characters 14 & 18, like these?:

If not tell us exactly what you do mean, if necessary give us a website link. You might mean something specialised which we are not familiar with.

As you can see, we are still struggling to understand your question. One possibility with a Dot Matrix printer is that some dots are not printing. This can make characters look very odd. If so it might be a faulty print head or ribbon. See here:
