I have written several posts regarding Zebra printers and the problems they have had with labels that rotate when they shouldn’t. According to this blog post in the SAP forums, this issue has been fixed in SP2. I don’t have the printer to test so if any of you who have had this problem can confirm that this is fixed, please let me know.
I have heard that Seagull Scientific provides free printer drivers for many zebra printers. These do not seem to have the problems described here. So that is another potential solution.
