Image Command Variant - ESC/P printers have small variants on how to send images using the image command. This option is only visible and configurable when a Graphic ESC/P or Native ESC/P printer is selected, so you switch between 2 possible variants to adapt to existing printer implementation. Normally this is by trial and error, since printers do not have this documented, so, normally, you can try with the option "Image Variant 1 (ESC * with Paper feed)" and if it does not print correctly, you can try to change to "Image Variant 2 (ESC * with Line Spacing)".
