Do Duplex printers capable of simultaneously printing both sides of A5 paper exist?

Hi,
Been trying to find one preferably a mono but nothing coming up in my searches. Most printers seem to be for sizes above A5 or only print A5 on one side at a time, no use for me as I am printing paperbacks. If someone knows of a particular model it would help. Thanks.
