Other than the output itself as you point out, the frame of what was printed is different between the left and right images you posted. Is the right-hand side really cropped off like that? Is it somehow applying some scaling factor?
I placed the original image and a scanned print of it next to each other in photoshop to show the difference in color and the horizontal and virtical lines that appear after printing. So, the image is mostly "needs to be (left) vs. "printed result (right). There is no cropping issue. I just didn't do a precise enough job in the juxtaposition.
Do you have any idea of why the print is so bad? I tried different papers too.
