He began the ritual. First, he went to the official HP Support site. He typed in the model number: M521dn. The page loaded with the enthusiasm of a dial-up modem. He clicked "Driver-Product Installation Software." A 347MB file began to download. At 12:47 AM, on a 15Mbps corporate line, it was a geological event.

The server room of Dunder Mifflin, Scranton, breathed with a low, electric hum. It was a cool, dark sanctuary of blinking lights, a stark contrast to the paper-strewn chaos of the bullpen outside.

He chose "Add a printer using TCP/IP address or hostname." He typed 192.168.1.110. Windows detected the device. "Select a driver," it prompted. The page loaded with the enthusiasm of a dial-up modem
