Dear @emre, I installed 4.1.18, did not modify anything in the settings and now the ticket has 4 square brackets before the logo bitmap and then the first set of lines of the bitmap are moved to the right in comparisson to the rest of the bitmap, and its not centered anymore. 4.1.17 was doing it OK.
Yes I’ve changed to fix vertical lines issue but it seems it didn’t solved. My printer does not have this issue so I’ll try to find a printer that have that problem. But I’m not sure why these square brackets appears.
