Label problems

Just bought a Brother ql700 labelprinter but are having troubles making it work correctly in Roastime.
Ptinted labels only have about a 1/3 of intended size.
Printing from the Brother labelmaker is ok with the same dpi settings in the driver.
Thr print preview in Rostime also looks correct.
After the newest update 1.179.0 I also now get a new problem the the RT freezes when trying to print sometimes.
Anybody else seen this ?
Thanks in advance
