here is the Printer Manual for Print NV Bitmap

 

[Name] Define NV bitmap [Format]

ASCIIcode FS q n [xL xH yL yHd1...dk]1...[xLxH yLyHd1...dk]n

Hexadecimal code 1C 71 n [xLxHyLyHd1...dk]1...[xLxHyLyHd1...dk]n

Decimal Code 28 113 n [xLxHyLyHd1...dk]1...[xLxHyLyHd1...dk]n

 

[Name] Print NV bitmap

[Format] ASCII code FS p n m

Hexadecimal code 1C 70 n m
