SOLVED. I removed the printer in settings, replugged and let it reinstall and it worked this time.
Brother HL-2140 laser printer
Windows 10
Attempt to print and immediately get a Windows pop-up saying "Error printing". The document appears in the printer queue window with Status "Error-printing".
Turned off printer. Unplugged, waited, replugged. Ran the Windows troubleshooter. Removed and reinserted toner cartridge. Checked for paper jam. No printer error lights. Reinstalled driver. Restarted the Spooler service. Rebooted computer. Removed and reinserted printer end of USB cable. Tried different USB slots on laptop. Tried printing different documents.
When I tap the printer ON light/button, it prints the diagnostic sheet below.
Any ideas?

Thanks!
