label printer Citizen CL-S521Z prints barcode "fuzzy" but rest fine

[exibar]

hey all,

    I have a Citizen Label printer CL-S521Z, it prints Amazon labels just fine...  but Paypal and Ebay labels, the barcode itself looks fuzzy a bit...  i'm concerned that they may not be able to be scanned properly by the PO along the way.

   This never happened before, and it's just with the barcode...  all the other lines are nice and crisp...  and this does not happen with Amazon barcodes, just Ebay and Paypal...

anyone have the same type of issue and have resolved it?  This printer is very close to the Zebra printers.

 thanks!

Yes, I understand it is a thermal printer, but do you have a laser or inkjet to output to?  This would help narrow down where the problem is coming from.
