Android Code Snippet Multiple printer codes on one line

I am working on a POS app, and it is almost complete.
I am working on the receipt portion at the moment and I hit a road block.
I need a left justified and I right justified on the same line.
catagory(left) price(right)

I have tried

    Dim ESC_JUSTIFY_LEFT  As String = Chr(27)&"a"&Chr(0)
    Dim ESC_JUSTIFY_CENTER As String = Chr(27)&"a"&Chr(1)
    Dim ESC_JUSTIFY_RIGHT  As String = Chr(27)&"a"&Chr(2)
Printer.AddBuffer_Writeline(ESC_POS.BoldOn  & ESC_POS.FontA_DoubleWide &  ESC_JUSTIFY_LEFT &  strCategory &  ESC_JUSTIFY_Right & strPrice )

but it does print correctly.

Any help would be appreciated
