Is it worth buying a inkjet printer if all I do is text printing, of say, 100 pages per year and that too irregularly? I heard that the inkjets get clogged up if not used regularly. So, should I go for laser printers (which cost 2x here) or stay with inkjets?
I spent years with one inkjet after another dying on me. Finally I got a laser printer and it was the best decision I ever made - and cheaper in the long run when you factor in the cost of ink and the cost of occasionally replacing the entire printer when it clogs up.
Running costs of printers are usually far higher than the purchase price. At home I have a small laser printer used for occasional printing of the sort of volume you are discussing. I have had it about six years and it is still on the original toner cartridge. For a shorter period of time I have owned an inkjet based copier/fax machine that gets used a bit more regularly and has had to have cartridges replaced a few times. On this basis I would recommend a small laser.
I wouldn't rely too much on anecdotal evidence though.
