We have a bluetooth thermal printer that is Zebra Qln220 that gets and prints Esc/Pos commands. When I wanted to print invoice text via bluetooth_thermal_printer and esc_pos_utils it prints but spaces between words totally different from invoice template. I have tested other device that is MHT P80 and it can print like the invoice template. How can I solve this? Is is about plugin or Flutter?

In addition printer prints “.” and sometimes “.!” top left corner of invoice.
