Modern? I'd say something sold in the past 5/10 years that supports
AirPrint.

One would think that a business machine supporting the LPD protocol
would cost a vendor pennies. After all, the vendor doesn't have to
do much when they already have the code to put in their firmware.

What is more interesting is why a user thinks that the LPD protocol
gives them something that IPP doesn't.
