●If you are acquiring an image from another device, such as a digital camera or another scanner, make sure the other device is TWAIN compliant. Non-TWAIN-compliant devices do not work with the HP LaserJet 1100A Printer•Copier•Scanner software.

●Be sure that you have connected the parallel cable that came in your package to the correct parallel port on the back of your PC. If you have another parallel port, try attaching the parallel cable to the other port. Make sure you have an SPP-(bi-directional) or ECP-compliant parallel port on your computer. An SPP parallel port is the minimum; an ECP parallel port is strongly recommended. For more information on your parallel port, please see the documentation that came with your PC.

●The HP LaserJet 1100A Printer•Copier•Scanner may not share a parallel port. If you have a sound card, external hard drive, or network switchbox connected to the same parallel port as the HP LaserJet 1100A, the other device may interfere. You must disconnect the other device to connect and use the

HP LaserJet 1100A or you must use two parallel ports on the PC. You may need to add another parallel interface card. An ECP parallel interface card is strongly recommended. Please see the documentation that came with your PC for information on installing an additional parallel interface card or resolving device conflicts.

1100A specifications

The HP 1100 and 1100A are pivotal laser printers developed by Hewlett-Packard in the early 1990s, marking significant advancements in printing technology of their time. Since their introduction, these models have garnered a reputation for reliability and efficiency, making them a staple in many offices.

One of the standout features of the HP 1100 series is its fast printing speed. The printers can produce up to 12 pages per minute, which was an impressive feat at the time of their release. This speed significantly reduced waiting times, allowing users to handle large-volume printing jobs with ease. Furthermore, the printers support a variety of media types, including letterhead, envelopes, and labels, enhancing versatility in print applications.

The HP 1100 and 1100A utilize laser technology, which ensures sharp and high-quality prints. The printers have a native resolution of 600 x 600 dots per inch (DPI), enabling crisp text and detailed graphics. This high-resolution output made the models particularly favored for producing professional documents and presentations.

Another key characteristic is the generous memory capacity. The HP 1100 typically comes with 2 MB of standard RAM, which is expandable, allowing for improved performance in handling complex print jobs. Users can adjust the memory according to their requirements, resulting in better efficiency, particularly in environments that demand high-volume printing.

The HP 1100 series also showcases a straightforward and user-friendly operation. The built-in control panel simplifies the printing process, allowing users to manage jobs intuitively. Additionally, with the inclusion of parallel and later USB connectivity options, integration with various computer systems was seamless, ensuring compatibility with existing office infrastructure.

Energy efficiency is another aspect worth noting, as the printers are designed to consume minimal power when idle, aligning with the growing demand for eco-friendly solutions.

Overall, the HP 1100 and 1100A stand out for their robust construction, high-speed performance, exceptional print quality, and user-friendly features, making them a trusted choice for small to medium-sized businesses in need of dependable printing solutions. Their impact on the printing landscape during the 1990s continues to be felt today, as they paved the way for subsequent generations of laser printers.
