Lightroom classic & Epson P900 driver using Tahoe forces Roll Paper mode

I’m running a printing workshop and had to setup a group of mac and windows computers to print on my Epson P900. The printer is using the latest firmware. All the Tahoe computers failed, everything else passed, here is what happened.

For each computer, we went to the Epson support page and downloaded the driver for their operating system. None of the computers had connected to the P900 before, so there were no old drivers present. Most of the Mac computers were running Tahoe 26.6.1 or 26.6.2, some were on Sequoia, PC’s were on Win11.

We ran the driver installers without issue. For all the Mac’s, we removed the AirPrint printers and added the Epson versions all went well.

We opened the Print module in Lightroom and started to setup a print. As soon as I selected Page Setup and chose the Epson P900, something was sent to the printer and it started operating. The printer raises an error on its screen asking for the roll paper adapter to be added. The error can be cleared down and the printer settles down.

We then finish setting up the print layout, paper size and source selections, media type etc and finally press print. Nothing happens. There is a job in the print queue but the printer doesn't print. I tried powering off the printer and re-starting to no avail.

Every one of the Tahoe computers does exactly the same. The sequoia Macs and PC’s work as expected.

I saw someone post something very similar but there was no resolution. Can anyone help?
