"Printer-only" models are well and good they are all about sheer text or business-document output to the exclusion of all else. You can break down lasers into four key types, defined by two questions: (1) Is the printer a mono-only laser, or can it do color, too? And, (2) is it only a printer, or an all-in-one (AIO) model that can print, scan, and copy (and perhaps handle faxes)? Laser models exist in all four combinations. Indeed, certain types of businesses, such as medical offices, may mandate laser printing for archival tasks and record keeping. It's also a good one if high-quality text printing matters most.
If you print a lot of large jobs, and stick mostly to text and clean graphics instead of color photographs, a laser printer is the right match.
Lasers are better suited to bulk text output: contracts, long research papers, book drafts. So, who would find a laser printer a more attractive proposition than an inkjet? In most cases, not the person seeking an occasional-use printer for motley tasks: at one moment to print a personal e-mail, the next to copy a color image out of a book, or to print photos. On the downside, lasers often have a significantly higher upfront cost, and they're nowhere near as capable as inkjets at reproducing fine gradients in complex color output such as photos. Still, laser printers have remained relevant by focusing on their traditional strengths: fast print speeds and reasonable costs per page (especially for text output), as well as the extremely clean look of the finished product.
