'Printing Images with ZPL code

I'm using ZDesigner to create my label and generate the zpl code. My label have several text boxes, a barcode, and a logo image. I used the generated code on this webpage -> http://labelary.com/viewer.html, and the output was fine. When I send the same zpl code to the printer (GC420D, installed as generic/text only) the logo image it's not printed. ZDesigner uses the command ^GFA to send the image to the printer, I tried with diferent extensions (.pgn, .jpg and .bmp) and the results is always the same, no logo.

Any ideas why?

Solution 1:[1]

here is my answer a little late but it may be useful for someone. I had a problem when performing a print service for an android application, when pasting the zpl code into the text editor I was not noticing that for some reason some blank spaces were being added, I realized until I copied the code and I viewed it here http://labelary.com/viewer.html after that I remove the blank spaces and the image could be displayed
