How to print on a printer with minimal margins around the edges?

Question

.NET

It is necessary to print an image on a receipt printer with minimal margins to the right and left of the edges.
I don't understand how it can be done programmatically.
Below is a screenshot of two receipts. On the left - printed by my program, on the right - through MS Word (or OpenOffice Writer):

It can be seen that my print has more indents.
I'm printing via C# PrintQueue, but I tried other options - I can't reduce the indents in any way. Shoveled already a bunch of examples on the Internet. Apparently, Word and Writer, somehow, are able to redefine them at the driver level, but how to do it from your program - no idea.

Answer 1

And if you reduce the indent margins in the printer settings when printing?
