Recommendation for thermal printer for barcode labels?

I’m in the market for an efficient barcode-label printer. So far I’ve been buying 1000 sheets of barcode labels (each sheet containing 30 labels), and I just put the sheets in a regular, all-purpose printer. But I’m wondering if I should switch to printers that specialize in printing barcode labels. Any downsides? Any brand recommendations? I see Rollo is popular; is it good?
