I need to print an graphical image using ESCPOS protocol. So far I have researched following commands available on my printer:

GS v 0 m xL xH yL yH d1 … dk

ESC * m nL nH d1…dk

Let's say I got following image where 0 and 1 represents a single pixel:

   |||||
-- 00000
-- 01010
-- 01010
---00000

  1. Which command I should use for this purpose?

  2. It is total unclear for me from documentations how to use these commands to print image and how printer reads my image and how I should pass that data. Command to print top first few lines of the image above with explanations of all parameters would be very helpful.

EDIT:

Regarding 1. - ESC/POS "Select bit-image mode" vs "Print raster bit image"

I was in your same situation, the documentation it's not clear. Finally I went to GitHub and found a library in Java that makes most of things with ESC/POS commands.

It worked for me. If you are not working with Java you can still look through the code and try to understand.
