That sounds like an incorrect duplex setting.
Set "Double-sided: long edge" in the print dialogue (not short edge).
If the message "Insert 2nd page" appears, automatic duplex printing is usually deactivated.
Check on the PC:
Printer settings → Printing preferences → Duplex printing → Automatic / Long edge.
On the printer itself:
Menu → Settings → Print → Double-sided printing → Automatic.
The problem should then disappear.
The printer cartridges are not included as standard with the printer, but setup ink cartridges are typically included when you purchase the printer. Here are the details:
- Setup ink cartridges are typically included when you purchase the HP OfficeJet Pro 9120e printer.
- However, separate ink cartridges such as the HP 937 or HP 937e series must be purchased for further operation.
The HP OfficeJet Pro 9120e (Ink, Colour) does support duplex printing. This feature is known as automatic two-sided printing or duplex printing, and it is enabled through the printer settings.
To ensure duplex printing is available, you need to:
- Check the printer properties in the Control Panel or Devices and Printers section on your computer.
- Ensure that the «Duplex Unit» or «Automatic Two-Sided Printing» option is enabled under the Device Settings or Printer Preferences tab.
This feature allows the printer to automatically print on both sides of the paper, which is a standard capability of the HP OfficeJet Pro 9120e.
Re 1: Yes, you can. I have just tried it again on the document feeder of the recently purchased 9120e.
Use the "HP smart" app on the computer and tick "double-sided document feeder". This will give you a 2X page PDF from your X-page A4 stack of paper as desired.
Have fun!
All 937 printer cartridges are compatible with the OfficeJet Pro 9120e, with the only difference being our suppliers.
