ZPL format UPS labels printing upside down on thermal printer from website

I’m stumped on this issue and hoping someone may be able to provide some insight as I feel like I’m missing something super simple…

I’m using a pretty standard UPS Shipping Plugin on my client’s site, https://deerdefeat.com, so when an order is placed a UPS label is automatically generated – you just have to go into the WooCommerce backend and click a button to print it. I’m printing the UPS labels via the ZPL option in the plugin’s settings on a Zebra ZP 450 thermal printer on a Windows 10 operating system. The issue is that the labels are printing upside down for some reason when generated from orders placed on the client’s website (see image). However, when making and printing a label directly from the UPS.com website, the label prints out correctly on the same printer using the designated UPS printer driver set-up (see image). Any ideas of why this might be happening or ways to fix the upside down label? The output just needs to be rotated 180 degrees…

FYI – I followed the instructions found in this youtube tutorial so ZPL files that open would be sent automatically to the thermal printer. I don’t know if that set-up would affect the orientation of the label, but wanted to share it. To summarize the video – I wrote a batch file that opens zpl files and sends a command so they print to the thermal printer automatically. Here is a photo of the batch file template. And here is a photo of the final command box.

Although I realize it doesn’t really affect the usability of the label (since the barcode can still be scanned), my client is insisting that I fix it so it prints out correctly and I’m stumped. I tried rotating the image in my printer’s preferences/property settings and had no luck. I have emailed the UPS plugin support team this question as well but I have a feeling they won’t be able to help.

Thanks in advance for anyone’s help on this!
