Muggles Guide - Don't stock up on ink!

If you have an inkjet printer you may be tempted to buy ink cartridges well in advance of needing them. If you see a special offer or if you are using the printer a lot. Its tempting... but be careful!

A little known feature of most modern cartridges is that a lot of them have a tiny little computer chip on them. This chip "knows" how old the the cartridge is. If the cartridge gets too old the cartridge will STOP WORKING!!!

I was really annoyed when I found out about this when a whole stack of expensive cartridges stopped working for no apparant reason! However I cannot totally be annoyed as recently a different printer that uses chip-less cartridge started going REALLY streaky. Turns out they were old and the ink had dried out in them.
