Hi, has my answer helped you? Can it be improved? You could consider marking it as the solution. – Patrick Kanzler Jul 09 '17 at 22:02

You could try python-escpos. This is a python-library that implements a low-level interface for ESC/POS. It wraps the ESC/POS-commands into python-functions and should be extendable if you need any special commands.
For your task you would probably want to create images and send them to your printer if it has no special function to print graphs. (And at least the ESC/POS-definition by Epson does not know any graph-printing-functions.)
python-escpos also supports serial printers and should work on both Windows and Linux.
