Thank

There are 2 methods of printing. The former is compatible with most printers. The second with some models.

Try both. There is a third method, but I still have to experiment with it, and it is not included in the library

I'm sorry. On the forum you will find many similar libraries for Bluetooth, try them and see the compatible one for your printer.

You need to know the command for cutting the paper. I do not know if it is the same for all printers

According to the document for the printer,
"• Paper cut by GS V m n."

but I do not know how to convert that to run with your library.

try this

B4X:

PrinterBT.AddBuffer_ArrayByte(Array As Byte(29,86,0,48))

or

B4X:

Dim N as int = 10 ' n × vertical motion unit
PrinterBT.AddBuffer_ArrayByte(Array As Byte(29,86,65,n))

Thank you for the conversion. Unfortunately neither of them cut the paper as needed.
Any other ideas would be appreciated

Try adding a zero after the command

PrinterBT.AddBuffer_ArrayByte(Array As Byte(29,86,0,48,0))

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

GS V m n
29=GS, 86 = V, m=56, n= (any number)

I changed the arraybyte to read
Stampa.AddBuffer_ArrayByte(Array As Byte(29,86,56,10))
but it still does not cut.

You need to find the right code for your printer, and sometimes the commands close with zero

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)

Is right,but no space. N = vertical motion

B4X:

Dim N as int = 10 ' n × vertical motion unit
PrinterBT.AddBuffer_ArrayByte(Array As Byte(29,86,65,n))

I appreciate all the help you are giving me,and if this ever completely works, there is a pot of coffee ion it for you, not just a cup.

I have the line

B4X:

        PrintBuffer=ESC_POS.BoldOn  & ESC_POS.FontA_Bold &  ESC_JUSTIFY_LEFT & TicketCatName   & ESC_JUSTIFY_RIGHT & SellingPrice
        Starter.Printer.WriteLine(PrintBuffer)

What I am trying to do is have the first variable (TicketCatName ) on the left justified and the second variable(SellingPrice) Right justified

But what I get is basically both variables printer as if it were concatenated.

Hi, I am testing your library and I see that there is no example Send_Buffer_to_Print_flush.
It's a mistake?
Regards.
