Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers.
Printing is needed, no one has doubts about it, but are they just as necessary as 20 years ago? This is a debatable issue, but certainly the market needs and consumer demand have changed a bit.
The production of marketing materials increased significantly - leaflets, banners, promotional leaflets, and advertisements - and decreased the production of books and magazines, mainly due to the popularization of the Internet. Will we wait for the times when printers, DTP operators and printing house owners will have to look for a new job?
Internet printing is the latest trend on the market and it is not surprising that users - more modern - are eager to use such printers. The advantages of this solution are certainly clear and predetermined conditions of printing, checking the files by the script and the speed of implementation.
Like every innovation, it also has its drawbacks - we can not check the printout but it is sent to us, which limits the possibilities of complaint. Sometimes software errors occur. However, the worst drawback is the lack of individuality in such online orders, and this is something that is valued by not one regular customer.
