Security warning for the same printer on iPhone 15 Pro

Hi,

looking for some help, my wife gets a security warning saying that the printer she is connected to does not appear to be the same printer that she printed to previously - and asks if she wants to continue. It’s the exact same printer as before but pressing continue does nothing and the printer won’t print anything.

if I do it on my phone I don’t get the error and printing works fine.

Her phone: iPhone 15 Pro running iOS 18.6.2

My phone: iPhone 16 running iOS 18.6.2

Printer: Epson ET-4800, firmware version XD02P9 (the latest one)

Any advice appreciated, thanks!
