Front and back print

[Danny_1]

Suddenly the printer no longer prints in duplex mode when I ask for it. It prints everything only on single sheets.

Welcome to the HP Community --

Check the Printer - EWS -

Ensure Paper Size & Type - Tray and Paper - are still set to a paper size / type that supports Duplex Printing.

EWS > HP Document / How-to

Use the HP printer Embedded Web Server (EWS)

EWS – Browser – Tray and Paper Management

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Settings > Preferences > Tray and Paper (Management)

Select / Adjust settings for Paper Size / Type

Model Dependent:  Advanced section

Click Apply to save changes

HP Technologies  - Stuck -  Not working as expected?

Consider:

Duplex printing – also used in booklet format – may need the following adjustment to assure that pages maintain their formatting and print on the page as needed:

-------------------------------------------------------------------------------

Control Panel > icon view > Devices and Printers

Right-Click Printer > Printing Preferences > Tab Advanced

OR

Windows 11

Settings > Bluetooth & devices > Printers & scanners

Select Printer >

Printing Preferences > Tab Advanced

Next,

UNCHECK HP Real Life Technologies

Click OK to save change

--------------  --------------  ------------- 

Duplex feature installed? (Model Dependent)

Control Panel > icon view > Devices and Printers

Right-Click Printer > Printer Properties > Tab Device Settings

OR

Windows 11

Settings > Bluetooth & devices > Printers & scanners

Select Printer > Printer Properties > Tab Device Settings

OR

Next,

Under Installable Options > Automatic Duplexing Unit > Select / Verify Installed > OK

Reminder:  Check Tray # = Installed

Duplex unit attached to the printer? (Model Dependent)

If there is a Duplexer unit attached to the back of the printer, consider re-seating (removing/replacing) the Duplexer box. If you do remove the duplexer, take a moment to check inside the printer cavity for tiny stuck paper bits – while stuck paper would normally result in a “paper jam” error, the condition might generate problems with printing duplex.

--------------  --------------  ------------- 

Duplex / Simplex options in Printing Preferences (Model Dependent)

Control Panel > icon view > Devices and Printers

Right-Click Printer > Select Printing Preferences

OR

Windows 11

Settings > Bluetooth & devices > Printers & scanners > Select Printer > Printing Preferences

OR

Next,

For Duplex:  Select a shortcut that provides the two-sided option and leave that shortcut highlighted (selected)

For Simplex (one sided):  Select a shortcut that does include NOT two-sided option and leave that shortcut highlighted (selected)

And / Or (if your printer software supported “custom shortcuts”)

Select a shortcut > Make changes that includes what you need / want (two-sided or one-sided)

NOTES

• Not sure where to start? Select Shortcut “Everyday Printing” or “Everyday Scan”
• Remember to check the settings within each Tab section
• Pay attention – not all Media types (kind of paper) and / or paper sizes support Duplex

Optional

If the printer supports the option,

Save the changed shortcut settings by clicking on the Master (currently selected shortcut) or use “Save As” (wording varies) to create a Custom shortcut

Leave the (new / custom) shortcut you want highlighted as the “default”

Click Apply / OK to save the shortcut
