Quick Christmas idea question for myself for a shipping label maker

Christmas question for myself. I’ve been looking into a thermal label maker (isn’t is more inexpensive w/no ink?) or a label maker in general to be able to print out my shipping labels quicker and easier and just slap them on the envelope - which leads me to my next question, I ship using a regular business envelope 9.5x4.13 -

Does anyone have recommendations for a shipping label maker that accompanies these labels for a business sized envelope? TYSM!!! God bless y’all.
