A:AnswerYes you can print a single label. It only uses tape made for this label maker and it is fairly expensive, but then not many labels of any type are cheap. Google PT-P700 and you will see where others have tweaked the defaults settings to get it to waste less tape between labels.
A:AnswerYes, there is a driver available to use the Brother PTP700, you can download the driver in the Brother support web site at https://support.brother.com/
