officejet pro 7740 error on USB

[Okinelin]

I can't get the printer to work in Windows 11 using the USB connection. Device manager shows question mark when the printer is connected and driver update link does lead to any solution.

Welcome to the HP Community --

I've never had to resort to a USB only connection --

The following is offered FYI and as a "hope it works for you" solution.

If you have a Wireless capable Windows computer, supported tablet, or phone, consider using Wi-Fi Direct.

Wi-Fi Direct uses the printer's own wireless radio to connect to your device wireless.

No Internet, no router.

AND

HP printer setup (Wi-Fi Direct)

Although Wi-Fi Direct does not provide access to all of the printer's features, it might suffice.

----------------   Relevant to a supported Mobile product (phone, tablet)   -----------------

Wi-Fi Direct might support enough of a connection to install the HP App on your mobile device.

Reminder:  No Internet with Wi-Fi Direct -- the information is provided FYI

---------------   Relevant to a supported version of Windows   ----------------------

• Consider installing the HP Smart application.

The Wi-Fi Direct connection should provide enough of what is needed to run at least some of the features in the HP Smart application.

At this writing, HP Smart has not yet been replaced with the HP App.

For now, Find the HP Smart app at the  Microsoft Store

AND

The full driver includes HP Scan and provides the foundation to print with other programs (for example, Word, Adobe Reader).
