"Do not feed a sheet of labels through the printer more than once. The
adhesive backing is designed for one pass through the printer."

I hate the idea of running labels through a laser printer once, but
maybe that is because I used to have to fix the damage it can cause.

I still keep an old LQ 24 pin printer around for printing labels but
it has been so long that I needed more than a couple at a time that I
imagine the ink is bad in the ribbons I have. For a "one off" label, I
print it on regular paper and seal in on the box with clear packing
tape.
That is a better label anyway.

I've had no problem running sheets of labels through an inkjet printer
multiple times. I can't even think of the last time I had any sort of
paper jamb.
