Barcode Problems -JW Tuna Lunch Tomato Salsa

This barcode has been printed so badly that it was only possible to decode one small section. It has been printed thermal transfer, which is an excellent printing method for producing high quality results. However, the print head appears to have blown elements, the barcode has been printed in the wrong orientation, and the printer has been running too fast. Disaster!

GS1 Business comment:
 

This code would only decode correctly in one very small section.
Mainly it decoded as a different barcode symbology (Code 39).
This code was printed in the ladder direction using a thermal printer with a print head that is in a diabolical state.
There are multi print head elements either block or blown.
In addition, the printer was running so fast the printhead did not have time to cool down between printing each element causing the bars to run into each other.
Bear in mind when printing ladder style, the printhead is only printing the width of every bar rather than the height.
