This usually means the print dialog’s Print button is not getting focus, so pressing Enter does nothing or activates the wrong control instead. In many apps, the fix is to use keyboard navigation to move focus back to the Print button, or to switch to a classic print dialog if the app offers one.

What to try

  1. Press Ctrl+P again, then use Tab or Shift+Tab until the Print button is highlighted, and press Enter.
  1. If you are in a browser, check whether the print dialog has a setting that restores the old behavior; one Firefox workaround is changing print.tab_modal.enabled to false in advanced settings.
  1. If the button seems hidden off-screen, try changing display scaling, moving or hiding the dock/taskbar, or resizing the window, since some print buttons can be pushed out of view.
  1. Update the app and printer driver, because printing problems can also come from outdated software or driver issues.

Why it happens

Some newer print dialogs do not place the cursor on the Print button by default, so Enter no longer triggers printing the way it used to. In other cases, the print button is technically there but not visible because of screen layout or UI scaling issues.

Fastest workaround

The quickest fix is usually: Ctrl+P, then Shift+Tab or Tab until Print is selected, then Enter. If that still fails, try the app’s alternate print view or update the printer software.
