I just followed the instructions to setup my Dymo 450 Turbo, but it keeps printing vertical. The paper I'm using is 30334. I went to Page Setup and followed the instructions in place, but I can't seem to figure it out. I use FireFox as a browser.
Our printing settings are based on using the recommended 30252 labels, as indicated on our site (http://www.scanpower.com/support/printer-setup/). You are using a different size which is causing your problem. We are working on establishing settings for other label sizes.
