Hi Vasanth,

It seems to be PCL (Printer Control Language).

The bad news is every printer vendor (HP, Xerox, IBM, Epsom, Canon, etc) have its own proprietary PCL, so you have to tailor it accordingly.

The good news is there are heaps of documentation available on the Internet and it is likely to be available in your new printer documentation too.

Good afternoon and good luck !

Thanks Andrew. I will check the printer documentation.
