Hi, currently, i am using this module in project.I have been trying to print a image but no matter the format that i use, i am having the same problem in the printing process : the result have horizontal lines with missing spots . The printer is working fine.

Can someone give me a help ?

@MaxJunior Tadaaaa, you are actually the first one admitting that he is using my code... Experienced similar troubles, and blamed it on the printer as the blank lines were not always there, but i will try to ionvestigate it

Ahaha, the code works fine. The only bug that i detected was in printing images. Thank you for you answer. If you fix this problem, please, let me know.

Hi, again, adding this line of code improves the quality of printed image. But the image still have 1 or 2 blank lines : Printer.append(Printer.ESCPOS_CMD.LINE_SPACE(24));

Thank your tip on line spacing saved my day, i am using my own code but couldn't get around horizontal spacing in the image. And it is i guess only visible in certain printers where the default line spacing is geared for printing text.
