Here is a link to the EPL2 Programming Manual, if you look at page 134, it describes how to set line mode via programming, which will persist (stay on) after a reset has been issued or the printer is power cycled. Otherwise, page 37, details how to make the change manually. Please try to make the change (I would think via programming might be the best way to start) and let me know if that change resolves the issue.
Hello Berverly, thanks for your quick reply, Thank you for the manual it's an updated version of the one I have.
If I read it correctly it say on a note in page 37 that

My apologies, I believe I may have been confused what your question was.
Were you asking for a way to keep the rotation change you made using the ZT command persist even after you power cycle the printer? Or were you asking if it was possible to set Line Mode on the GX420t. Also, are you using EPL1 or EPL2?
Can you send the ~HQHO command and read the response and post it? That will help me help you find out if line mode is supported on your GX printer. You can also try just sending the OEPL1 command, followed by a carriage return and then sending your label.
