However, today I learned how complicated it can be to buy a new printer. There are two ways: don’t think too hard and buy one that looks like it will do the job; or analyse the pros and cons of several models and look into the on-going costs ie printer cartridges. If you overdo this bit you can then get into a spiral of calculating cost per page per colour cartridge – an important piece of data as this does vary significantly – but worrying over fractions of pence differences is an indication that you have gone a bit too far. Then there is the issue of whether the cartridges are refurbs or genuine – and would the refurbs work ? I’m sure there is some sort of copyright protection going on here, but there seems to be a big market in this area.
