Total dollars per student for this category will grow at a healthy rate, from $9.27 per student in 2006 to $16.23 per student in 2011 for a compound annual growth rate of 12.3 percent. "Again, the simpler the printer, the better, which is why a letter-size printer will cost less than an oversize model." "This is where working out your needs before going shopping will pay off," says Sintic. In the same vein, consider whether letter-size printers (8.5-by-11 inches) will suffice for your school or if some of your classes (such as art) need oversized printing capabilities. So unless you really need color printing, stick to monochrome. What about color? Well, since color printers use multiple toner cartridges, they cost more to operate per page than monochrome (black on white paper). "This is why buying a 4,800 dpi printer to only produce documents doesn't make sense 600 dpi will do." He adds that some manufacturers have designed their printers to print at 600 dpi and still produce quality 4,800 dpi by interpolating the dots, optimizing image detail and printing speed. "Just remember that the more dots per inch, the more detailed the image printed," says Sang-Woo Kim, printer specialist at CDW-G. Dpi describes how good the printed image will be in terms of its resolution. What kind of quality are you looking for?Ī second printer acronym that will dog you is dpi, or dots per inch. A 60-PPM printer isn't much help if it takes 30 seconds to get the first page out!ģ. "Such high-volume users can't afford to wait for reports that take two minutes per page to print." In contrast, classrooms that print single images every now and then don't need to pay a premium for speed.Īnother point to consider is how long it takes for a printer to produce its first page. "Speed is important for a teacher who needs to print 30 to 40 progress reports at a time," says Nancy Sintic, district technology coordinator for the 4,200-student Ashtabula Area City Schools in Ashtabula, Ohio. Short for pages per minute, PPM is the best indicator of how much, or how little, a printer can do for the money. When buying printers, one acronym persists: PPM. The Lexmark E450dn prints 35 pages per minute.
