Average home PC users are equipping themselves with more and more multifunctional peripherals, to the detriment of traditional A4 printers. In 2005, the market saw an increase of 27% in the number of units sold-according to the market research company GfK-when in the same period the increase in A4 inkjets was only 12%. There are several factors behind this success. A primary one is that multifunction printers are now barely more expensive than conventional printers, but offer much greater versatility. In fact, Canon points out that the average sale price of a conventional printer is $128, when that of a multifunction printer is $127! This is somewhat of a paradox.
