Printing postage on Dymo LabelWriter 450 Turbo problems
Before the latest update, Firefox was correctly printing Dymo LabelWriter 450 Turbo labels. AFter the recent update, the printer prints but the labels are compressed 50% horizontally so that they only print on the left half of the label. This is inappropriate for USPS labels (or any labels for that matter).

I would say check on the software label update. Could be something needs to be update to work with newer Browser updates.
No there are no software updates from Dymo. Software works just fine with other browsers. Problem is with Firefox, not Dymo.
Unless another user of the same hardware can reproduce the problem finding a fix will not be soon here. Otherwise you also need to contact Dymo support and ask them.
