[Hewlett-Packard LaserJet IID printer]

Model Data
Model NumberHP 33447
Introduction DateNovember 1988
Original MSRP$3,595
Replaces ModelHP LaserJet 500 Plus
Replaced by ModelHP LaserJet IIID


The Hewlett Packard LaserJet IID, a PCL level 4 language printer, is based on the Canon RX engine. This engine is capable of duplex printing (both sides of the paper), hence II"D" for Duplex. The LaserJet IID has 14 built-in fonts, which is eight more than the Series II. Most font cartridges for the II are useable in the IID, but emulation cartridges are not. The video interface that comes with the JetScript for the Series II will not work in a IID. The video interfaces that come with LaserMaster controllers and others that access only the video lines will work in the II or the IID. The cover set is the same shape as that of the Canon LBP-8IIR, but the color is a shade lighter.

This diagram shows how paper is fed through a duplex printer system.


The LaserJet IID was the first HP printer to include the ability to rotate fonts from portrait to landscape. Earlier printers had to have the fonts bitmapped in each form. Cartridges such as the HP ProCollection have Helvetica and Times Roman programmed in portrait orientation only, and that's the only way they work in the original LaserJets and Series II. These fonts can be used in both portrait and landscape orientation on the IID and on newer HP printers such as the IIP and III. See the HP Font Cartridge page for more information.


The HP LaserJet IID has been discontinued, but The Printer Works can build them from parts at special request. Refurbished printers are in like-new condition and come with a Six-Month Warranty. For a price quote, select the printer's part number in the ordering information table.

The IID is the first LaserJet to use a controller designed and manufactured by HP rather than by Canon. The style of the board fabrication is typical of HP and not Canon. Traces are gold plated and they make sharp 90 degree bends. These characteristics have been a trademark of boards designed and built by HP. Manufacturing cost was reduced by combining into a large ASIC many of the TTL parts found on Canon designs. Incorporation of this chip protects the board design from copying and makes repairs difficult for board repair houses who do not have access to spare ASICs.

The HP LaserJet IID uses the same toner cartridges as all other SX-based printers. HP Toner available


There are many font cartidges made by HP for the HP LaserJet family. When you want to increase your printer font collection, see our catalog page on Font Cartridges from Hewlett-Packard.


The LaserJet IID printer uses the same shaped paper trays and high-capacity feeders as all other SX-based printers. All versions are physically interchangeable, but there are slight color differences. (See also Diagram 300.)

You can also buy third party high-capacity feeders for paper or envelopes, as well as an output stacker, to add productivity to SX, RX and TX printers. The sheet feeders can hold up to 1500 sheets; the envelope feeder up to 250 envelopes. The stacker extends your printer's output hopper, allowing it to stack up to 500 sheets.


The IID uses the same RAM expansion boards as the Series II and there is only one RAM expansion slot. Compatible memory boards are listed below. Interestingly, the IID accepts the same PostScript cartridges as the IIP and the III, but IIP and III memory boards will not work in the IID.


The LaserJet IID controller does not have as many upgrade options as the LaserJet II or III. PostScript can be added with the PostScript Emulation cartridges from HP, Pacific Data Products or UDP. To improve print quality, the controller can be exchanged for a LaserJet III/IIID controller (LaserJet III/IIID use same board). With a LaserJet IIID controller there are many excellent scalable type cartridges available.

Note regarding memory and the controller upgrade:
If you purchased extra memory for your HP II/IID, which comes with only .5 MB on board, please remember that this extra memory will not work with the III/IIID controller. However, the III/IIID board does come with 1MB of memory standard. If you want more than that, you will need to buy III/IIID compatible RAM. You can add up to 4MB to the III/IIID controller board, which gives you two RAM expansion slots. But the II/IID printers only have one memory access panel, while the original III and IIID printers have two access panels. If you expand your RAM using a single 4MB RAM board, this will not matter. But if you want to expand the memory using two equal RAM boards to reach the maximum 4MB, you will have to remove the printer's bottom panel to access the second memory slot on your new controller. Therefore, it would be easiest to install a two-board RAM expansion at the same time as the new controller board.


[LaserJet IID with envelope feeder installed]

The LaserJet IID can have an automatic envelope feeder attached to feed up to 50 envelopes at a time. It is shown here. The envelope feeder of the IID receives power and control signals from the DC Controller via a round hole in the bottom case.

NOTE: LaserJet IID envelope feeders are not interchangeable with IIID envelope feeders. The external cable connection system has been replaced with a connector above the upper paper tray and the wires are routed to the DC Controller internally, rather than externally. Also, the physical mounting system has been changed. The IIID envelope feeder has snap-in rods rather than hooks to hold the feeder to the face of the printer.
