Question about HP OfficeJet Pro 8125e

The HP OfficeJet Pro 8125e and the 8122e are technically almost identical: both are multifunction printers with duplex printing, ADF, WLAN/LAN/USB and the same paper cassette capacity. The differences are mostly not in the hardware, but in sales or in details such as enclosed cartridges, warranty and service options or the connection to HP services such as HP+ and Instant Ink. For practical use, both devices deliver the same performance, so the 8125e is not a "better" printer, but simply a slightly modified model variant.
