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.
The LaserWriter is a laser printer with built-in PostScript interpreter sold by Apple, Inc. from 1985 to 1988. It was one of the first laser printers available to the mass market.
LaserWriter (March 1985), included 13 fonts in ROM and 300-dpi resolution.
In 1985, Apple produced their first laser printer, the LaserWriter (later known as LaserWriter I). Apple didn`t make the first consumer laser printer, they made the fourth, after IBM, Xerox, and HP.
The printer`s laser projects your print onto a drum. A drum then uses static electricity to attract the dry toner to the drum`s cylinder. The drum then rolls the toner onto the paper to create your print. The toner powder is melted and pressed onto the paper with heat from the fuser as it goes through a set of rollers.
Laser printers process data such as documents and materials created on a PC and output them on paper. Multifunction laser printers (MFPs) are laser printers equipped with additional functions such as copying, scanning, and faxing.
A laser printer is a popular type of computer printer that uses a non-impact photocopier technology where there are no keys striking the paper. When a document is sent to the printer, a laser beam “draws” the document on a selenium-coated drum using electrical charges.
Answer. Answer: Apple Laser Writer is an example of a DTP Hardware.
The IBM 3800 is a discontinued continuous forms laser printer designed and manufactured by IBM. It is significant as a product because it was both the first laser printer manufactured by IBM, and the first commercially available laser printer.
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.
We know laser printing best because we invented it. Specifically, Gary Starkweather invented the laser printer in 1969 at the Xerox research lab in Webster, New York.
Traditional printmaking techniques include woodcut, etching, engraving, and lithography, while modern artists have expanded available techniques to include screenprinting.
Prints are produced by drawing or carving an image onto a hard surface (known as a matrix) such as a wood block, metal plate, or stone. This surface is then inked and the image is transferred to paper or another material by the application of pressure, thus creating an impression, or print.
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.
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. Unlike ink, which is sprayed onto paper through fine jets, toner creates a crisp, resilient and long-lasting image.
Laser printers use toner powder instead of dye or pigment-based ink. Laser printers produce electrostatically charged dots on a light-sensitive drum which attracts toner powder. The toner is transferred to the paper and fixed by a heating process.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.

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

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.
