Android Question Not able to print image using SD BT Printer lib

[microbox]

Hi, I'm using SD BT Printer lib and using the given example. I'm able print text with no problem but no success with image( qr code). I tried to resize it using

Printer.AddBuffer_Bitmap(LoadBitmap(File.DirAssets,"qr.jpg").Resize (100, 100, True),0)

But prints out like garbage characters.

Can you print the qr code of the example?

In the first posts there is an example source. I always recommend that you first use that code and do all the tests to check compatibility with your printer

Can you print the qr code of the example?

This is the code I'm using to print

Sub RadioButtonMIX_CheckedChange(Checked As Boolean)
    Printer.ClearBuffer
    Printer.AddBuffer_Writeline("TEST - Mixed Text and Image")
    Printer.AddBuffer_Writeline("012345678901234567890123456789-F")
    'Printer.AddBuffer_Bitmap(LoadBitmap(File.DirAssets,"qr.jpg"),0)
    Printer.AddBuffer_Bitmap(LoadBitmap(File.DirAssets,"qr.jpg").Resize (100, 100, True),0)
    Printer.AddBuffer_Writeline("END PRINT")
    Preview.Panel.Height=Printer.Preview.Height
    Preview.Panel.SetBackgroundImage(Printer.Preview)
End Sub

I'm not able to print the image in the given example. But prints the text with no problem.

Why didn't you do the test before the donation as I had written to you in private?

No worries...this printer is not my own(just borrowed) I will look for another, and not really in a hurry.

it must be a printer using Esc / Pos language. There are many models from 30$ upwards.

The printer you showed me requires a specific library
