We have the Dymo purchased at the school stuff our little ones to label. The unit came quickly. Also the system to create the labels on the computer and then print out is great. And all still without having to install software (not the Mac).
So unpack the Mac connected, launched program, created label, pressed on Printing ... The machine is humming and comes out a tape. Only that the yellow stripe unfortunately something is missing: the imprint.
After well we can use it to write on anything rather the part goes back again.
