Airprint. Weird, bad prints with duplex mode

Hello,

I'm facing issues when i print via AirPrint with duplex (double side pages) with my iphone 12 / Ipad Pro M4 under ios18.0.1 ipados 18.0.1 . 

One docx document containing 2 pages . When printing with airprint on duplex, second page is printed twice, then fist page is printed partially without the image. 

Tested on same devices with epson smart panel app works perfectly

Tested with my old Ipad air on ios 12.x with airprint, had no problem : prints are perfect.

Issues also seen with pdf documents.

No issues seen with one page print mode with airprint

Printer is epson ET-8500 with latest firmware.
