My Epson printer is stuck mid-print, what's the first thing I should try?

The simplest first step is to cancel the print job from your computer. Locate the printer queue (usually accessible through 'Devices and Printers' or 'Printers & Scanners' in your operating system settings) and cancel the current job. If that doesn't work, try power cycling the printer – turn it off, wait 30 seconds, and turn it back on.
