HP LaserJet M209dw Mono Wireless Printer with 30 ppm Print Speed and 1200 x 1200 dpi Resolution 41.3 Error Fix: Unexpected Paper Size

Error code 41.3 on the HP LaserJet M209dw Mono Wireless Printer with 30 ppm Print Speed and 1200 x 1200 dpi Resolution means: Unexpected Paper Size. The printer detected a different paper size than what was configured in the print driver settings — the paper size set in the driver (e.g., Letter, A4, Legal) does not match what was actually loaded in the tray; either load the correct size paper, or change the paper size setting in the print driver and on the printer control panel to match the loaded paper; this error also occurs when the paper guides in the tray are not adjusted to the correct paper width
