imagePROGRAF TM-300 won't do borderless printing anymore

[Angelamather323]

After two years of flawless, borderless printing, my printer is suddenly producing borders on both sides of the paper. I am printing from my MacBook Pro M3 (macOS Sequoia) onto a 36” roll. I’ve tried making changes to the settings on both the printer itself, and in the printer dialog box on my computer, but the problem continues. I have the latest drivers installed and my firmware is up-to-date. Thoughts?

No answer. This is why I hate forums.
