So there is no misunderstanding, this is what my code is, and it still does not cut the paper.
B4X:
Stampa.Initialize(Me,"Stampa",Encoding.Windows1252)
Stampa.AddBuffer_Writeline("How are you?")
Stampa.AddBuffer_ArrayByte(Array As Byte(29,86,0,48,0))
Stampa.SendAllAndClose
according to https://www.rapidtables.com/convert/number/ascii-hex-bin-dec-converter.html, the conversion should be
GS:29 V:86 m:109 n:110
which means my bytearray should be
Stampa.AddBuffer_ArrayByte(Array As Byte(29,86,109,110))
is that correct, also should ther ebe a spce(20) in between each char (29,20,86,20,109,20,110)
