The **HP LaserJet 5100 printer** is a high-quality office printer designed for fast, wide-format printing, supporting media up to 11 x 17 inches (printed on 12.8 x 18.5-inch media). It produces high-resolution printouts at 1200 x 1200 dpi, suitable for CAD drawings, graphic proofs, and detailed spreadsheets. The printer delivers up to 21 pages per minute for letter-size documents and 11 pages per minute for 11 x 17-inch documents with a first page out time under 13 seconds. It features a 300 MHz processor with up to 192 MB expandable RAM and networking options for workgroups via a 10/100Base-TX Jetdirect card. The printer weighs about 50 lbs and measures approximately 24.6 x 18.5 x 11.9 inches[1][5].

Additionally, the **HP PageWide XL 5100** is a different model under the “5100” name, offering 20 pages per minute in both black & white and color at the same 1200 x 1200 dpi resolution. This model is more oriented toward large-format wide printing with a top stacker option[3].

The HP LaserJet 5100 series has been discontinued, but supplies and accessories might still be available[4].

The “HP Smart Tank 5100” referenced in one video is a different, modern printer line unrelated to the LaserJet 5100 and focuses on ink tank technology rather than laser printing[2].
