I use an HP Envy 5541 wirelessly for printing from my Windows 10 laptop.
Sometimes when I print, the item is added to the print queue but no printing takes place. The printer status according to Windows is Attention Required. There is no information given on the printer display.
I have also noticed that the number of documents pending when I hover over the printer icon in the system tray is often inaccurate, stating that there are more documents in the queue that there really are (but never fewer).
My fix for this, which has worked several times, is to run the Troubleshooter available from 'Devices and Printers'. The Troubleshooter runs and reports that it could not find the fault. However, printing magically starts before the Troubleshooter has finished.
When this fix does not work, I briefly press the power button the printer to 'wake it up' (the display illuminates) and then re-run the above wizard - printing then commences.
What could be going on and is there a way to stop the situation arising where I need to run the Troubleshooter to unblock printing?
NB: I have the latest HP ENVY 5540 All-in-One Printer series Firmware Update EN5540_R1831A.exe downloaded from support.hp.com
NB2: I have run the HP Print and Scan Doctor tool from the HP website. It erroneously claims the printer is out of paper, which is untrue and disagrees with the printer's own display. Ultimately the Print and Scan Doctor signals that it is unable to resolve the issue and recommends re-installing the printer software. I have already done this, and so am no further forward.
NB3: Restarting the print spooler service does not correct the issue
