imagePROGRAF PRO-300 borderless printing no longer working

[Roebu]

After two or so years of trouble-free borderless printing, my imagePROGRAF PRO-300 printer is now producing a white border around every print.

This was working fine until the end of October (?). I have checked and double-checked all settings. I'm printing from Lightroom 14.0.1 on Windows 11 onto A3+ size paper (13" x 19").

The only change I am aware of is a recent firmware to the printer which is now on revision 2.000.

Any ideas, anyone? Thanks . . .
