We use these labels for occasional large mailings, but more frequently for individual or small group mailing. They print nicely, and do not jam in our laser printer. They also are easy to peel off, but they don't peel off unexpectedly and get stuck where they shouldn't. The only issue I have with them - since we usually only print a few labels at a time, the label sheets get multiple runs through our printer. After a couple of runs, the labels start to take on a grayish appearance and don't look quite as clean.
