Laser printer buy
The attack of online printers Internet printers grow like mushrooms after rain - no wonder, because the vision of sending files by the site, which will itself inform us whether everything is okay in technical matters (formats, colors, size, etc.).
However, not all printers have the option of ordering directly through their website, and this error and the background of competitors fall short, badly.
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.
However, the price you have to pay for the possibility of online orders can be deterred by smaller printing houses and printing plants from such an investment.
Laser printing in Wikipedia
Laser printing is an electrostatic digital printing process.
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.Źródło: https://en.wikipedia.org/wiki/Laser_printing
Standards in print and not only
Standards in every industry and business are important. Imagine that we buy a monitor and its input does not match our video card, even though it has the same type. That's why certain standards apply.
In polygraphy and graphics, such standards also exist - appropriate definitions of CMYK colors - key for the appropriate color reproduction. Specified in advance formats for printing leaflets and business cards, so that they are comfortable and as uniform as possible.
Without standards, even leaflets could be completely unreadable and even repulsive.
