Hi All

How y'all doing? Happy New Year BTW...

Attached is a POS device I am using... it prints well but I would like to be about to change the font and/or size of the text.

I did some google but... anyway what I picked up is that I have to send some commands together with the string that I am passing to the printer...

Anyone with links/guides/command?

example: String result = "This is to be printed"; how to add commands to this string to increase the font size?
I am still researching...

Thanks
Eric

 

Does it respond to the 'AT' commands?
Send "AT" and see if you get an "OK".

@AlbertHall Thanks for your reply. Not sure. How do I set AT command to that? it's been a very long time since I dealt with these kind of stuffs.
And what if it does not respond to AT commands?
