**HP LaserJet printers** are a long-established line of laser printers introduced by Hewlett-Packard (now HP Inc.) in 1984, recognized as the world’s first commercially successful laser printers[1]. They use xerographic laser technology with print engines primarily supplied by Canon.

The LaserJet family includes various models designed for different needs:

– **Home and small office models** (e.g., LaserJet 100 and 200 series) focus on compact size, reliable black-and-white printing, moderate speeds (around 20 to 30 pages per minute), Wi-Fi connectivity, and features like two-sided printing and automatic document feeders[2].

– **LaserJet Pro series** targets small work teams and home offices, offering multi-function capabilities (print, scan, copy), wireless options, and enhanced security and management features[3][5].

– **LaserJet Enterprise series** is designed for medium to large businesses and departments, prioritizing high-speed printing (up to 75 ppm), high-volume capacity, extensive security (HP SureStart, intrusion detection), and multiple connectivity options. These models often have larger color touchscreens and hardware extensibility for integration purposes[4][5].

HP LaserJet printers are known for their speed, reliability, and affordability across a wide range of applications, from personal use to enterprise environments. They leverage HP’s proprietary Printer Command Language (PCL) for print jobs, which historically contributed to their market success by enabling earlier and cost-effective printer models compared to competitors[1].

In summary:

| HP LaserJet Category | Target Use | Key Features | Print Speed (approx.) |
|————————–|————————–|—————————————————|——————————|
| LaserJet 100 & 200 Series | Home and small office | Compact, Wi-Fi, 2-sided printing, auto document feeder | 20-30 ppm |
| LaserJet Pro | Small teams, home offices | Multifunction, wireless, security, management | Varies, typically 20-45 ppm |
| LaserJet Enterprise | Medium to large business | High speed, robust security, large capacity | Up to 75 ppm |

Thus, HP LaserJet printers provide reliable laser printing solutions scaled for different business sizes and user demands[1][2][3][4][5].
