hi,
those guidelines given are excellent to purchase a new system, but i can tell you regarding things to know before print.
Know Before You Buy
Saving money on printing starts before you buy your printer.
Once you start looking at certain models, make sure you check the recommended print volume; if you typically print 100 pages a day, you wouldn’t want to buy a printer that's rated for 500 pages a month.
Replacement ink cartridge costs represent a major part of your long-term printing expenses. Expect to pay $10 to $40 for an ink cartridge, and $60 or more for a toner cartridge.
Don't judge a cartridge just by its price; the number of pages it can print is just as important. That figure will change depending on how much ink you use on a page; the industry-standard is 5% coverage per page for each color. Some companies make yield information available on the Web along with other printer specifications; others will provide it if you ask.
Many cheap laser printers come with starter cartridges that last anywhere from 60 percent to as little as 33 percent as long as a regular cartridge. If you know you'll be printing 100 pages per month, find a printer that comes with a full-size cartridge
The heavier, brighter or more specialized the paper is, the more expensive it will be. You'll pay as little as a half-cent per page for typical, 20-pound office paper, to as much as a dollar for an 8.5-by-11-inch sheet of glossy photo paper.
Save the good stuff for final prints; for everything else, use the cheapest paper your comfortable with. Third-party brands often cost less per page than the printer manufacturer's media, always test it on your printer to make sure you like the results. You might go through a full pack to do this,.
