print bulk postage (not labels)

The issue I am having is printing postage, not labels. I purchased a roll for postage (Netstamps) from stamps.com and I wanted to print a bunch at one time so I do not have to change the roll in my thermal printer from labels to stamps each time I need a stamp. It seems excessive / wasteful to print a full label for a small letter when I just need postage. Is anyone else having the same issues?
