The office grew restless. The senior partner needed his quarterly review printed in 20 minutes. Frustrated, Maya dug into the printer’s embedded web server (typing the printer’s IP into a browser). There, under Firmware Version , she saw it: 2015.09.12 .
But after a Windows 10 update over the weekend, the M521dn went rogue.
She tried PS. Nothing but a single sheet reading: %%[ Error: undefined; OffendingCommand: showpage ]%% hp laserjet mfp m521dn driver
But that wouldn’t have made a good story. And she’d never admit it.
The printer was running firmware so old it predated Windows 10 entirely. No wonder the drivers were having an identity crisis. The office grew restless
To this day, the HP LaserJet MFP M521dn runs quietly in the corner, printing 15,000 pages a year. And every time someone says, “The printer isn’t working,” Maya just smiles and says: “Have you tried the Universal Driver?” If you’d like, I can also explain the M521dn driver is so finicky (hint: it has both PCL and PostScript personalities) — just ask.
She printed a test page.
She downloaded the latest firmware (2020.03.22) from HP — but you can’t update firmware over USB if the driver is broken. Classic chicken-and-egg.
