The Dawn of a New Printing Era
Before sleek office printers became commonplace, printing documents was often a loud and slow affair. Workplaces relied on impact printers, which used metal characters to stamp ink onto paper through a ribbon. These machines were noisy, produced low-quality output, and were ill-suited for computer use. In 1969, Xerox engineer Gary Starkweather envisioned a different approach: using a laser to create images and text directly from computer data, bypassing the need for physical striking. This concept eventually gave birth to the laser printer, a defining office technology of the late 20th century.
A Problem Hidden in Plain Sight
By the late 1960s, businesses depended heavily on computers, but printing technology lagged behind. Most computer printers still used impact-based technology similar to typewriters. According to The Engines of Our Ingenuity from the University of Houston, Starkweather realized that Xerox's photocopying technology could be adapted to produce original pages from computer instructions—a fundamentally different approach. However, Xerox management initially rejected the idea, arguing that a copier company had no business in computer printing. Despite this, Starkweather continued refining his concept.
The Move That Changed Everything
The turning point came when Starkweather moved to the newly formed Xerox Palo Alto Research Center (Xerox PARC). The Computer History Museum notes that the basic concept was developed at Xerox's Webster Research Center before the move, but at PARC, away from management resistance, Starkweather built the first functional laser printer in less than nine months. This prototype printed at two pages per second—remarkably fast for the era. Speed was crucial; any new office technology had to serve a practical business purpose. A device that quickly produced crisp, clear documents had obvious commercial potential.
Why Was the Laser Printer Revolutionary?
The genius of the laser printer lay not just in using a laser beam, but in its ability to convert electronic information into a fully printed page. A focused laser and optical components create images on a photoconductive drum, which transfers toner to paper, producing far more detailed and consistent output than impact printing. Starkweather leveraged Xerox's xerography technology not to duplicate pages, but to draw new ones from computer data. This insight became the basis for early laser printers at Xerox, enabling businesses to generate high-quality documents like reports, letters, invoices, and presentations on demand.
From Lab to Office
The first commercial laser printers were large and expensive, designed for high-volume business use. The Xerox 9700, introduced in the 1970s, printed two pages per second and replaced slower line printers for statements and invoices. As computers became commonplace in the 1980s, companies like Xerox, IBM, Canon, Apple, and Hewlett-Packard developed more affordable models for typical offices. This evolution made laser printing accessible to a broader market.
The Quiet Revolution That Transformed the Office
In hindsight, the laser printer impacted more than just printing. Michigan State University notes that Starkweather's invention redefined commercial printing and modern office work, making high-quality digital documents feasible at scale. Today, the ease of generating perfect printouts from computer files is commonplace, but it owes much to Starkweather's innovation. What started as frustration with noisy machines evolved into a technology that bridged the digital and physical worlds. Over half a century later, this concept still underpins a vast share of the pages printed worldwide.
