LaserWriter (March 1985), included 13 fonts in ROM and 300-dpi resolution.
Design. The LaserWriter was the first major printer designed by Apple to use the new Snow White design language created by Frog Design.
Apple`s first printer was the Apple Silentype, released in June 1979, shortly after the Apple II Plus. The Silentype was a thermal printer, which used a special paper and provided 80 column output. Also compatible with the Apple III, the Silentype was a rebranded Trendcom 200.
Forty years ago, Xerox introduced our first commercial laser printer, called the Xerox 9700. We demonstrated this groundbreaking technology at the 1977 National Computer Conference in Dallas, Texas. That was the world`s first introduction to what is now a fixture of offices everywhere.
The HP LaserJet was the first desktop laser printer, introduced in 1984 at about $3,500. Nothing like it existed previously, and it created a totally new printer market—similar to what the HP-35 handheld calculator had done 12 years earlier.
18.4.
A semiconductor diode laser is currently used in laser printers as the light source.
The laser printer was the first to be invented and was done so in 1969 by Gary Starkweather while working in the Xerox product development team. His idea was to use lasers to imprint an image onto a copier drum which would then be transferred onto paper. Hence, the name `Laser printer`.
The first electronic printer was the EP-101, created by Japanese company Epson in 1968. It was a tiny printer, only 164 millimetres in width, 102 millimetres in height and 135 millimetres in depth and weighing just 2.5 kilograms. The printer was created by Epson (Shinshu Seiki Co.)
Goldsmith and inventor Johannes Gutenberg was a political exile from Mainz, Germany when he began experimenting with printing in Strasbourg, France in 1440. He returned to Mainz several years later and by 1450, had a printing machine perfected and ready to use commercially: The Gutenberg press.
How a laser printer works. They work by using a heated wire to positively charge a drum, which is then passed over by a laser that reverses the charge in the areas that it hits. The now-negatively charged areas of the drum represents the image or text that is to be printed.
Theodore Maiman made the first laser operate on 16 May 1960 at the Hughes Research Laboratory in California, by shining a high-power flash lamp on a ruby rod with silver-coated surfaces.
The Apple LaserWriter was the first laser printer available to the mass market. The Apple LaserWriter with its built-in Adobe Postscript page description software was one of the key elements in the desktop publishing (DTP) revolution.
Laser printers use either black-only toner or black and color toners. Unlike some inkjet printer cartridges, each color for laser printers is sold in a separate cartridge. The standard colors for a laser printer are cyan, magenta, and yellow.
Lasers are classified into 6 types based on the types of medium used in them, and they are: Solid-state lasers. Gas lasers. Liquid lasers.
Selective laser sintering is an additive manufacturing (AM) technology that uses a high-power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. SLS 3D printing has been a popular choice for engineers and manufacturers for decades.
A few meters have a maximum of 1,000 volts but laser printers typically produce more than that – up to 3,000 volts is quite normal and higher voltages perfectly possible.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer. Toner is a fine dye power that is melted onto the paper.
The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.

HP Officejet Pro 8500 Wireless with fake paper jam
ANSWER : HP Officejet is by far one of the frustrating piece of equipment I have ever owned. I bought it as unused in the package, at that point no warranty left. less than 6 months and 500 pages the white cog gear wheel broke. Luckily with instructions in this site I manage to glue it back together. Then I bought new ink – problems started as they were not original HP 30$ per cartridge. Ordered originals (here in China), took over one week to get them. Then found out that printhead needed to be replaced => more than 100$ spent. Still constant problems: If my wife kids print, I need to be stand-by as you never know what happens. Really an Office level equipment. After cleaning one paper jam I broke the encoder tape, took me another 4 hours to get it fixed. Then broke the cog gear again and got it displaced. Another 4 hours. Only reason I am not throwing this s***t out of window is that there are still ink left. Luckily this drinks them like a horse, for sure I will no more buy new ink. I will get a new laser instead, and not from HP. About cog wheel fixing: make sure that the white wheel is positioned correctly so that the small torx in shaft goes into the slit in the white wheel. When fitting the black cover back, make sure that the white washers on both sides fit into to slits of the black cover. Good luck.

Magenta toner smeared all over printouts
ANSWER : Forgot to add, I have a spare Fuser kit I can install but I’m guessing that won’t fix problems with magenta toner spilled all through the guts of the machine. Is it worth installing?
