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?
