SD: BT Printer Bluetooth

[aviario]

Hello, I tested your library with an Intermec Pr3 printer and it does not print the bitmap

Thank

 

[Star-Dust]

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

 

[aviario]

I have used both methods and it does not print

Thank you

 

[Star-Dust]

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

I am trying you lib on a bt printer,but cannot figure out how to cut the paper after the printing is complete

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

 

[rkmoray]

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.

Tomorrow I'll take a look and let you know

?????

try this

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

or

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

 

[rkmoray]

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

 

[Star-Dust]

Try adding a zero after the command

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

 

[rkmoray]

So there is no misunderstanding, this is what my code is, and it still does not cut the paper.

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

 

[Star-Dust]

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

 

[rkmoray]

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

 

[Star-Dust]

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

 

[rkmoray]

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)

 

[Star-Dust]

Is right,but no space. N = vertical motion

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

        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.
