So you are bypassing the print driver or printing directly to (say)
COM1 ?

I've not heard of those before, and cannot find anything about them

This page looks helpful

And this is better as it is definitely ESC/P and goes on to ESC/P2

>Anyone know how could I use this commands?.

My understanding is that ESC/P prints graphics as a stream of bytes

Esc * mode n1 n2 Data

The mode is documented in the second link above, n1 and n2 are I
believe a WORD containing the number of columns
eg: typically bytes * 8

Your Logo is probably not a 2 colour bitmap, but you can convert it
into one by using the method: BitMap.Mask( Colour )

The background/transpararent colour is probably
BitMap.Canvas.Pixels[ 0, 0 ]

You can get at the underlying pixels using the Bitmap.Scanline[ 0 ]
property, I would copy those into a String

It is over 20 years since I last used Epson graphics, but from memory
it was not particularly difficult
