Answer first
Check the default printer, clear stuck print jobs, confirm paper size, restart the printer and computer, then print a test page from system settings instead of the original app.
Many devices keep old or duplicate printer entries. Select the active printer and avoid sending jobs to an offline duplicate.
Cancel stuck jobs and try one simple test page. Large PDFs or old documents can block everything behind them.
If the printer recently updated, verify the driver, paper size, tray, and connection type before reinstalling.
Quick FAQ
Why does my printer say connected but not print?
The selected printer, print queue, driver, paper setting, or connection path may still be wrong even if the device appears connected.
Should I reinstall the printer first?
No. Try default printer, queue, test page, and paper settings first.
