Is there any possible way to print bigger font size in TM-U220B by using escpos (Python3) ? I have tried so many time and yet still cannot print bigger font size or image as well. Thank you very much if you could helped me.
Only the following commands can be used with TM-U220.
It seems that you can specify 3 types of double width, double height, and double width height, but it may not be supported.
Please try it.
It may be possible to double width.
ESC !
There are two types that can be specified for image printing: 8-dot single-density or 8-dot double-density.
And it seems that it only expands in the width direction, not in the height direction.

FS p [obsolete command]
Please click the TM-U220 button in the Select your printer model [-] table on each of the above pages for model-dependent details.
In addition:
This is a QA article for other POS apps, but it seems that enlarged printing is possible.
