The LaserJet 5Si MX's performance was on a par with the other 24-ppm contenders. It produced 20.1 ppm on our Multiple Simultaneous Jobs test, placing it in the middle of the pack. For even more demanding departmental networks, consider the 24-ppm LaserJet 5Si Mopier. A multicopy job is sent once to the printer, which then collates the job electronically. Based on the LaserJet 5Si, the LaserJet 5Si Mopier adds a 420MB hard disk, a 2,000-sheet bin, multibin mailboxes, a stapler, and a duplexer.
Users can have the printer print, collate, and staple output without having to use a copier.
In hands-on testing the LaserJet 5Si Mopier performed well. We ran a series of jobs with calls to several trays to its mailbox bin. The stapler's special cube of 2,000 pins forms into staples on demand. The Mopier is a serious contender for demanding departmental applications. The workhorse of the Hewlett-Packard family is the HP's 5000 D640.
