The first computer printer emerged from experimental teleprinter technology in the mid twentieth century, driven by the need to produce permanent records of digital data. Before this innovation, users relied on manual transcription or punched cards, making automated output devices a breakthrough for business and research environments.
Early electromechanical printers were adapted from existing teletype systems, bridging the gap between mechanical communication equipment and digital computing. Recognizing key milestones and technological lineages helps explain why certain designs endured while others faded.

| IBM 1403 Printer | 1959 | Chain Printer | Set the template for high speed line printers in commercial data centers |
| Xerox 9700 | 1977 | Laser Printing Engine | Connected with mainframes to produce the first networked office pages |
| Canon Cat / ARC Printer | 1987 | Raster Image Processor | Pioneered scalable text and graphics for desktop publishing workflows |
Origins in Teleprinter and Teletype Technology
The first recognizable computer printer was essentially a teleprinter, most notably the Teletype Model 33 KSR, adapted for early computers in the 1960s. These machines combined a keyboard, printer, and paper tape reader to allow operators to interact with systems using familiar typewriter mechanics.
By repurposing robust typebar mechanisms originally designed for telegraph offices, engineers gained a practical way to output alphanumeric data at human readable speeds. This lineage is crucial, because it established the concept of a peripheral that could sit alongside a mainframe and provide instant, physical records of digital events.
IBM 1403 Chain Printer and High Speed Commercial Output
How the IBM 1403 Changed Data Center Printing
Introduced in 1959, the IBM 1403 printer became the workhorse of commercial computing by using a rapidly moving chain of characters to strike an inked ribbon against paper. Its ability to print hundreds of lines per minute made batch processing reports far more practical for banks, insurers, and government agencies.
The design influenced peripheral standards for decades, shaping expectations around reliability, line density, and compatibility with fixed width fonts. Although noisy and physically large, the 1403 demonstrated that centralized output could scale to meet the demands of enterprise data processing.
Xerox 9700 Laser Printer and Desktop Publishing
From Experimental Engine to Office Network Hub
Released in 1977, the Xerox 9700 was one of the first laser printers built for office environments, leveraging advances in photoconductivity and electrostatic imaging. Unlike earlier typebar systems, it produced text and graphics by precisely controlling a laser beam on a photosensitive drum, enabling much finer detail and smoother tonal transitions.
This shift paved the way for desktop publishing, where designers could preview and print high quality layouts without relying on external service bureaus. The 9700 also supported network connectivity, linking powerful minicomputers to shared output devices and foreshadowing modern print server architectures.
Canon Cat and the Rise of Raster Image Processors
Integrating Print into Personal Workstations
In the late 1980s, systems like the Canon Cat incorporated dedicated raster image processors that translated screen content directly into printable pages. These embedded printers, often based on compact thermal or inkjet technologies, blazed a trail for future all in one devices that combined computing, scanning, and high quality output.
The convergence of screen and paper output in a single user focused machine reflected a broader industry trend toward treating print as an intrinsic part of the digital workflow rather than a separate peripheral. This perspective continues to shape product roadmaps for modern workstations and creative tools.
