Our parent company has banned the use of Java JRE being installed on any company computer due to licensing issues. However, we rely on labels from UPS for shipping.

I wanted to know if anyone could point me to where I can find info on how their UPS Thermal Printing App works so I can develop an in-house alternative on OpenJDK to use instead, given we cannot link their webpage to our UPS Label Printer any longer...

Thank you.

I had gotten a secondhand thermal label printer when I first started selling, and initially purchased a box of labels as well. After I had bought the blank labels I realized you can get free labels from UPS. No big deal, I figured I would just use them all up and then start using the roll that UPS provides.

Well today was my last label of the ones I bought previously. I went to switch out the roll, and feed the first label until it recognizes where to stop at the perforation, it didn’t want to stop. It just keeps feeding until halfway into the second label.

I had a few extras blank ones from the labels that worked and kinda made a makeshift roll to deduce that it was just the UPS labels that didn’t work. I taped two goods ones, a ups one, and then a good one. To my surprise it recognizes the two first labels and then after seeing the ups label it does the same thing and fed halfway into the last label. I’m thinking it has something to do with the thickness of the UPS label somehow, as it does feel a few mil thicker.

So does anyone here utilize the free UPS thermal label rolls and have a machine that works well with them?

Thanks
