Print logo to zebra printer

[shena]

Hi experts out there, I'm using a zebra printer, model TLP 2844Z. I need to print my company logo on a label. I've been trying this for the past two weeks and no idea what I'm doing wrong with the code below :( Other lines are printed except for the first line is not being printed(the logo). Please... anyone help me point in the right direction.

'Open the port:
        Open "LPT1" For Output As #1
        
        Print #1, "^XA^FO15,127^XGR:CO_Logo2.GRF,1,1^FS" & _
                  "^FS^FO15,200^ADN,36,20^FD" & b & _
                  "^FS^FO241,200^ADN,36,20^FD" & i & _
                  "^FS^FO121,401^ADN,36,20^FDRMA" & "^FS^XZ"
              
        'Close the port:
        Close #1
