The Sharp AL-1644 is a monochrome multi-function printer, scanner, and copier designed for a single user home or office environment. This printer can handle a large range of paper sizes that should make it suitable for professional monochrome printing for office uses and has an internal tray that is designed to keep space usage confined to the footprint of the device, making it ideal for small home office use. The AL-1644 prints and copies at a reasonable speed and functions as a high quality colour scanner. This model is no longer available new, though it might still turn up as a refurbished or used unit.
The Sharp AL-1644 can print at up to 12 pages per minute and copy at up to 16 pages per minute on A4 paper with a standard resolution of 600 dpi. This printer is a bit larger than many other printers from this time frame, at 59 cm x 57.7 cm x 65.3 cm. Optical scanning resolution can go up to 600 x 1,200 dpi, with interpolated scanning at up to 9,600 dpi. The printer connects through a parallel or USB 1.1 interface, and does not come with on board networking. Sharp AL-1644 toner is sold as either a cartridge or a refill kit with drums available separately. The AL-1644 only supports Windows, with no support for Linux or Mac OS X.
This older printer can be a great choice for individuals looking for a multi-function machine that will work with an old version of Windows at home. The lack of networking can make the printer simple for a single user to run, and the separate but easy to find Sharp AL-1644 cartridge and drum assemblies make keeping this printer running inexpensive. The AL-1644 has a good set of features for an older multi-function machine, and could serve a single user who needs to print frequently quite well. This printer supports quite a few paper types, which could be a real asset for some users.
The Sharp AL-1644 is not particularly compact or low on energy usage, which may end up being an issue in a confined space. This printer won't work with newer operating systems, and Windows only support excludes many people with computers that don't run Windows. In general, most users who can find something that will work with their machine would probably be better served by a more modern multi-function printer.
