This printer works like a dream—delivers a crisp, beautiful page every 3.5 seconds.
Dependable and Fast, LaserJet 4Si Makes the Perfect Business Partner!

The 4Si is a pedigreed draft horse of a printer! Built with a steel frame, it is solid and reliable with a 75,000 page per month duty cycle. At 17 pages per minute, this workhorse is fast too. Even complex pages can be delivered every 3.5 seconds. It stands up to heavy use and handles up to twenty users with ease! The 4Si comes with two 500-sheet paper trays and a 500-sheet output bin. The high speed Bi-tronics parallel interface will give you fast performance from a PC. Use an optional HP JetDirect Card to bypass the server for even faster network performance. You can also buy a duplex unit (see special offer below) for double-sided printing.

Of course, the 4Si MX has all the same advantages, plus built in PostScript Level 2 and AppleTalk! It work brilliantly with your Macintoshes and in mixed platform networks, with LocalTalk, EtherTalk, and other supported network operating systems. Talk to our sales people about your specific networking needs.
