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.
He originally received pushback from his employer, Xerox. But his invention eventually became nearly ubiquitous in every office and home.
LaserWriter is a family of laser printer designed for Apple and Macintosh computers. It was released in 1985 and was very similar to HP`s LaserJet, using the same Canon CX printing engine. LaserWriters offer fast printing, Ethernet connectivity, high resolution and excellent color output.
Answer. Answer: Apple Laser Writer is an example of a DTP Hardware.
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.
Specifically, Gary Starkweather invented the laser printer in 1969 at the Xerox research lab in Webster, New York. Soon after, he transferred to Xerox Palo Alto Research Center (PARC) and developed a prototype for the Xerox 9700: our company`s first laser printer, which came to market in 1978.
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.
Quality: While inkjet printers are considered powerhouses when it comes to high-resolution color printing, laser printers do produce solid color and black and white results.
Like a photocopier, laser printers read the electronic data from your computer and beam this information onto a drum inside the printer, which builds up a pattern of static electricity. This attracts a dry powder called toner onto the paper which is then fused using heated rollers.
The printers laser beams your print onto a metal drum. The drum uses static electricity to attract powdered toner to the drums cylinder. The drum rolls the toner onto the paper in the form of your print. The toner is melted & pressed onto the paper by heat from a fuser as it passes through its rollers.
Laser printers are faster than inkjet printers too. Print speeds are denoted in pages-per-minute (PPM). Laser printers have print speeds of 14 PPM and higher. The basic laser printer can print about 30 to 40 pages per minute, whereas high-end models churn out more.
macOS (originally named “Mac OS X” until 2012 and then “OS X” until 2016) is the current Mac operating system that officially succeeded the classic Mac OS in 2001.
Apple iOS is a proprietary mobile operating system that runs on mobile devices such as the iPhone and iPad. Apple iOS stands for iPhone operating system and is designed for use with Apple`s multitouch devices.
Apple`s retail stores would need additional repair space and staffing. And printers introduce a large class of technical support problems that Apple currently avoids. And after all that, unless Apple made the print engine, it wouldn`t make the ink, and that`s where all the money is.
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.

A semiconductor diode laser is currently used in laser printers as the light source.

The HP LaserJet was the world`s first desktop laser printer.

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.

Yes, laser printers can print in monochrome or full color. Just keep in mind that color laser printers are more expensive because they require new toner cartridges for each color, as opposed to just a black toner cartridge for monochrome laser printers.
It was designed for data centers, where it replaced line printers attached to mainframe computers. The IBM 3800 was used for high-volume printing on continuous stationery, and achieved speeds of 215 pages per minute (ppm), at a resolution of 240 dots per inch (dpi). Over 8,000 of these printers were sold.
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.
Laser Printers work with CMYK toners only. inkjet printers and ink printers used for professional photo printing, for example, can use additional colors to achieve better printer results. Among other things, brighter gradations of magenta, cyan and also gray are used.
Color Laser Printer or Black & White Laser Printer

As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.

Inkjet printers typically run at a lower price point than laser printers, and printer ink is cheaper than toner. However, laser printers and toner have a longer lifespan despite their high cost. Meaning laser toner cartridges have a lower cost per printed page than printer ink.

Epson, sudden cannot recognise cartridges error
ANSWER : Hi, I have exactly the same problem than you, I’ve been trying to solve it since 6 months. I have an Artisan PX730 WD, and the genuine cartridge can’t be recognized all together. And status monitor indicates same thing than you.

Product not working suddenly
ANSWER : Since there aren’t any parts available and this looks pretty much fatal, it would be time to buy a new printer.

Blank page with strips
ANSWER : That would be a bad wiper blade in the drum unit. Either the black or color drums. Whatever color or black the stripes are.

printing blank pages
ANSWER : You can’t let an inkjet printer sit that long. Try flushing the heads. Take out all the ink tanks and to the right of the assy. you will see a plastic lever. Lift it and it will release the heads. Take it to the sink and using hot running water, flush it from top and bottom several times. Then blot it dry and reinstall.

HP Color Laserjet blank pages – only jetdirect page
ANSWER : What about the engine test? To do that, drop down the front tray. Feel around on the left side at the top and you’ll feel a little plastic dongle. If you lift up on that it will initiate an engine test page. That will be a page containing lines of each color.

Display blank
ANSWER : I think PCA just means Printed Circuit Board Assembly, it can also be listed as PCB but either way it’s the same thing.

HP Officejet 860 printer printing blank pages
ANSWER : First check the exact ink levels, replace if any one are low or empty.

LED display is blank
ANSWER : Check the connections to the display and the DC controller. Could be either a bad controller or a bad display. Unfortunately, you can’t swap either with your HP 4.
