Overview

If you are printing a scanned image or copying an image and the quality is not as you expected, you may have selected a resolution or gray-scale setting in the Copier/Scanner software that does not match your needs. Resolution and gray scale affect scanned and copied images in the following ways:

	●	Image clarity
	● Texture of gradations (smooth or rough)
	● Scan and copy time
	●	File size
	Resolution is measured in dots per inch (dpi) while gray scale is
	measured by the number of grays possible to create a transition from
	black to white. You can adjust the scanner resolution up to 300 dpi.
	Gray scale can be set at 1 (black and white) or 8 (256 levels of gray).
	Listed in the table, “Resolution and gray-scale guidelines,” are simple
	tips you can follow to meet your scanning and copying needs. Also
	see “Resolution” and “Gray scale” to learn more about these topics.

Note	Setting the resolution and gray scale high can create large files that
	take up disk space and slow the scanning or copying process. It is
	important to determine how the scanned image is going to be used.

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.
