问题
I'm working on some code to print an image from an Android device to a Bixolon SPP-R200. From what I can tell, it emulates ESC POS. I noticed that there are two commands for printing images. "Select bit-image mode" (ESC *) or "Print raster bit image" (GS v 0).
What's the difference between these two commands? Why would I choose one command over the other?
