Image is not printed well, neither in column mode nor raster mode.

Hi contributors,
when we tested receipt print with image, logo at the top,
in raster mode it doesn't get printed at all. might be issue related with Thermal Printer itself. so we tried column mode.

this time image did printed, but it's like this.

It is probably an issue with how your printer supports the ESC/POS spec. What kind of printer are you using?

I have the same issue both with an Epson TM-T88V and a cheap Jolimark TP-510. Always happening in column mode. The Epson doesn't have the issue in raster mode, the Jolimark doesn't support raster mode so i can't test it.

Which dithering algorithm?
