问题 I am having issues decoding DLE EOT 1 im thinking its the bit order and the lack of leading zeros import serial x = 1 while x: time.sleep(3) ser.write("\x10\x04\x01".encode()) bytesToRead = ser.inWaiting() data = ser.read(bytesToRead) while data: print(data) print(bin(int.from_bytes(data, byteorder="big"))) print(bin(data[0])[2:]) data = "" so this is what is returned when in ready and online status: b'\x16' 0b10110 10110 this is what returns when the Door is open 'assume OFFLINE status': b'

ESC/POS “Select bit-image mode” vs “Print raster bit image”

不羁岁月 提交于 2019-12-12 01:36:10
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.

Why would I choose one command over the other? 来源: https://stackoverflow.com/questions/41039088/esc-pos-select-bit-image-mode-vs-print-raster-bit-image
