need help printing UPS shipping labels

[Dr. Michael J. Chudobiak]

Does anyone here successfully print UPS shipping labels from the UPS 
online shipping tool?

I find that when I try this with Firefox, epiphany, or Chrome on F19, 
the barcode-containing section of the label is generated as a 728x416 image.

If I use Firefox or IE on Windows, the same label is generated as a 
1400x800 image.

The UPS scanners won't recognize the barcodes in the smaller images, so 
I have to print from Windows.

Any ideas? Is this some odd javascript default-image size setting that 
differs with OS?
