These models also feature a 20-30W power saving (stand-by) mode, which was not included in the original Laserjet 4. The printing mechanism was also improved to allow increased tones of grayscale. The original 20 MHz processor was also upgraded to 25 MHz, with the addition of Hewlett Packard's Memory Enhancement Technology. This also provided the option for duplex printing (automatic double-sided printing) with the purchase of an accessory (HP part number C3157A). The LaserJet 4 Plus (4+), released in 1994, was the LaserJet 4 with the improved Canon EX+ engine which increased printing speed to 12 PPM. It prints eight pages per minute, and the user cannot extend the feeders. Introduced in 1992, this is the original LaserJet 4 with the Canon EX laser print engine. A quality abrasive is needed to ensure no particles are shed into the mechanism. Another alternative is to use coarse quality abrasive paper such as those used by belt sanders to roughen the surfaces of the rollers. The heat shrink extra diameter pulls the paper quicker and resolves the wear/slip issues. Replacement kits for these rollers are easily obtainable and can solve the problem.Īn alternative is to enlarge the roller slightly by using heat shrink over the output rollers. In many cases, the delivery rollers (upper and lower) in the upper or final stage of the paper exit are worn or unserviceable. Printers that exhibit the "accordion" or "washboard" paper jam problem with the paper tightly concertinaed or folded in the exit paper path (often behind the rear access door) generally have problems with the paper exit mechanism. However, any printer mechanism is subject to wear and degeneration, and typically printers still in use have now seen long service (the machine being discontinued with the introduction of the Laserjet 5 in 1995). The engine has a high monthly duty cycle (20,000 pages) and it is not uncommon to find units still functioning well after a million or more page impressions. The EX (and EX+) print engine is known for its reliability and longevity, and in comparison to earlier generations of laser printers, these machines have acquired a 'workhorse' reputation.

However the driver for the HP LaserJet 4 exists in most, even older, software products and is a popular substitute driver for other PCL compatible printers.
#Hp 4 plus driver series
The LaserJet 4 series was discontinued in the 1990s, and Hewlett Packard recommended the HP LaserJet 5 series as a replacement for the 4 series. Hewlett Packard dominated the laser printing sector during this time in part due to their reliability, relatively affordable pricing, and the spread of LaserJet 4 models from personal use up to heavy business use. The LaserJet 4, especially the 4/4M/4+/4M+ models, have become known for their durability, mainly due to their reliable construction, as well as the printers built-in PCL (and optional PostScript) printer language support which is still used in computers to this day. Hewlett Packard also released an upgraded version of the LaserJet 4/4M known as the 4 Plus ('4+')/4M Plus ('4M+'). There are also PostScript variants of these machines with the '4M' designation, where M stands for, but is not limited to, usage with an Apple Macintosh. Additional models included the 4Si model, created as a heavy-duty business printer, and the 4V model, a B-size printer for desktop publishing and graphic artists. The 4 series has various models, including the standard LaserJet 4 for business use, the 4L for personal use and the 4P for small businesses.
