More on unwinding the label backing paper from the Labelroo: see images attached.
I actually used a short length of thick straight cane, fine sawcut to start followed by lengthening into a split with a penknife blade, just long enough to hold & grip the backing paper.
Remove the Labelroo handle.
Trap the backing paper in the slot, then tighten cane / dowel into the driver chuck.
At a slow speed on the "screwdriver" setting, wind up the backing paper.
Don't be tempted to go at high speed as friction could build up between the steel shaft & plastic body of the Labelroo.
A splash of silicone lubricant would perhaps help.
Worked for me.
