Printing Japan Post on a thermal printer
A generated image is fine for a one-off. For a production run you want the barcode rendered by the printer at its own resolution, sized in whole dots so the narrow bar lands on an exact dot boundary. LabelInn does that on Zebra, TSC, Toshiba and Epson hardware, and it can drive one label per row straight from your data.
THE PROBLEM, THEN THE FIX
Japan Post: it looks right on screen, so why will it not scan?
A code that is slightly too small, too tight or the wrong type is the usual reason a scanner refuses it.
The problemThe code is drawn at a size that suits the screen, not the scanner.
