Most habitancy buying a new printer today are looking at a selection in the middle of a Laser printer and an Inkjet printer, although there are more types out there, more of this later.
Soho refers to "Small Office Home Office", an roughly arbitrary category, since there are big overlaps with other "categories" of users at both ends of this definition.
Laser Printer Price
For instance, a home user who is a hobbyist, with an interest in photography will want a color printer capable of printing on photo paper, with uncostly resolution, to match his digital Slr. The printer he would need no ifs ands or buts falls in the Soho category.
Similarly, a large enterprise with many employees might have a large office staff, all of whom would have a Pc, and many of whom would need a printer. Many printers in this situation would be networked together, so that they could be controlled from a central point for job switching and maintenance purposes. The network feature is now suitable in this type of printer, but they are the same printers which are used by the "small office" with perhaps 2 or 3 printers, shared by maybe 6 people.
Within the categories of "inkjet" and "laser" printers, there are many variations of features, which we can check out to settle what type is suitable for our purpose. Before we look at these two main categories, it is a good idea to look at what we will be printing. Most users, these days want to be able to print in color, so we will take a quick look at how the color is achieved.
The suitable is that four colors of ink are held in the printer, ordinarily known as Cmyk or Cyan, Magenta, Yellow and Black. Why K for black? It stands for "key" as the other colors are keyed to the black level. This ideas is known as the "Additive Process", that is the primary colors are added to one another, in dissimilar proportions, to furnish all the other colors. Black is theoretically not necessary, as the three primaries together should furnish black, however, the density of colors required and the unknown "whiteness" of the paper make it much more economical to use black as well. Of procedure the majority of text is in black, so that is someone else good reason. Or to put it someone else way, it is cheaper, printer price is important!
This color ideas is in dissimilarity to the more familiar Rgb, or Red Green Blue ideas used in your Tv and computer monitor. Rgb is a "Subtractive Process", that is, the proportion of colors is altered to furnish all the other colors by subtracting from or reducing, say the intensity of the red. Once again we can have a "black problem" early Lcd screens had a qoute fully removing all the light to furnish black. This was noticeably poorer than modern plasma screens, but has now been fixed. Why this is important, is that in order to print out an image seen on your screen in Rgb, the data must be converted to Cmyk in order to furnish the printer with the definite information. Maybe you've noticed the printout is not all the time the same as the image on the screen?
In part 2 we see how the two main types of printer handle this color system
