Yup, I only have the older 450 (not turbo) and it works as fast as I can print them but I print one label at a time as the item is packed. If you print 20 labels at a time then put them on maybe its a bit faster... no clue. I saved a couple bucks and went with the basic one. It does all USPS 1st class and priority labels besides the APO which you need half a page and sign.
