I bought this PC USB connected label printer to replace a handheld brother label maker. The handheld unit worked nicely but I found the small display to be very difficult to read, and the operation to be a bit difficult.This PC version is so much easier to use, has more capability, uses the same excellent TZ style tape and can be battery powered for easy movement between computers. No software install is required, the device appears on the computer as a disk drive that contains the label making editor (lite version) program. Super easy, works really well, and making the labels on screen with a real keyboard is just so much easier than fussing with the handheld unit. If you want to make more complicated labels you have the option of installing the full version of the label editing software on your computer, but so far I have found the light version which requires no install to be perfectly adequate for my needs.This unit has made making labels fast and easy, and I recommend it highly.
