Question about OfficeJet Pro 9010 - 414309

Hello, if you Google it, the "e" is the successor that is offered at a lower price and can print duplex (i.e. sheets are turned over and printed on the back). I don't think ours can do that, but it's only used in the office to print invoices and make copies.

I don't know. You would have to ask HP this question directly.
