How do I clear a print queue that's stuck and causing an 'error state' for my Epson printer on Windows 11?

To clear a stuck print queue, go to 'Settings' > 'Bluetooth & devices' > 'Printers & scanners'. Select your Epson printer, click 'Open print queue'. In the print queue window, go to the 'Printer' menu and select 'Cancel All Documents'. If this doesn't work, you might need to restart the 'Print Spooler' service via the 'Services' application in Windows.
