This may not be your answer, but it often works with issues like this. Just turn off the printer, unplug the printer, wait 15 seconds and plug back in and turn on again.The unplugging is intended to drain any residual power and memory left in the printer after turning off. This sort of re-sets the printer. Then, be sure that your specific printer is chosen in your print setup window. You may have additional printers connected and power outages may set it to default or to another printer.
