UPS shipping labels in EPL format?

I'm using the UPS Shipping Tools to generate shipping labels... I'm able to successfully generate the label data (and I'm able to print the labels in GIF format), but I'm wondering how I could save EPL formatted label data, so a thermal printer (UPS Thermal 2844 from Zebra) can use it? I tried saving the raw data in a text file and printing it, but that failed. I've also contacted UPS tech support, but they haven't been really helpful. Does anyone have any insight on this or point me in the right direction?
