Welcome to the HP Community --

True - After a decade of service, the much loved Scan and Capture application was retired May 1, 2024.

HP Smart - Windows - does have a sensitivity to "Dark Mode" -- the app might not start and instead displays a "white" window.

=========================

1)  HP Smart - Windows

Instructions...

>>> How to Use >>>    HP printer setup (HP App) 

>>> Terms of Use >>>  HP Smart – formally HP Connected – Services Terms of Use

NOTES

• If you are running High Contrast or “Dark Mode” and the app will not open at all, try switching to None (for contrast) or “Light” for mode. 
• After the application opens, set up the printer –
• Later, if you wish to do so, try setting the mode back to your preferred setting.

References - Windows 11

Settings > Accessibility > Contrast Themes >> Switch to None

Settings > Personalization > Colors > Choose your mode = Light

The Small Print

NOTE >> Some settings are the same for HP Smart and its eventual replacement application HP App.  Settings might serve the same purpose and might be located in different places within the HP App.

• Read the Terms of Use document to understand the conditions of using HP Smart / HP App products.  For example, in the HP Smart application, find the link in HP Smart > Settings (gear) > About > Click on the link for Terms of Use
• Read HP printer setup (HP App) >> Read FAQ - including - What are the requirements to set up a printer using the HP App?
• If using VPN >>Disconnect from Virtual Private Network (VPN) connection before downloading.
• Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.
• Enable Bluetooth (on your computer) at least for the initial HP Smart / HP App setup: Enable Bluetooth on your computer or mobile device so that HP Smart / HP App can detect the printer during the setup.  Source: How to scan with an HP printer > FAQ > Why can't I connect my wireless printer or scan over the network?
• HP Smart / HP App requires that you sign into the application using your HP Account credentials.
• When working through a Browser to access HP Smart / HP App, be sure you have Cookies enabled.  If cookies are enabled and you are having trouble, clear Cache and Cookies.   And / Or … Try a different Browser – assign that Browser as the Default. (Note:  Chrome not working?  Use / Assign a different default Browser.)
• Ensure that Network and Sharing are enabled. 
  • Example Settings > Network & internet > Advanced Network Settings > Advanced sharing settings
  • Private Network > Network discovery = ON
  • Checked “Set up network connected devices automatically”
  • File and printer sharing = ON
• Where possible, HP Smart / HP App might benefit having the Full Feature Software / full driver printer software installed.  For example, full driver provides access to Shortcuts and Printing Preferences.
• “Share” to email – Before using Share, add your sender email address to the standard Windows Mail application (not New Outlook).

• Document includes the HP Smart / HP App application download links for Windows and Mobile devices, plus an FAQ section to assist with questions / issues.

Help Here:  Unable to download and install the HP app
