Had a problem with an old printer. Each time we went to print it had pretty much dried out - new cartridges or ink. 3rd party cartidges were really hit and miss, refilling original cartidges were also the same and often resulted in a new cartridge or set.
When our son was doing his GCSE's and A levels it was getting ridiculous in costs as while we may not have so many dry out, the rate he could use them was mad.
I went out and bought a colour laser instead. Only last year (year 4) did I need to replace the cartidges it came with and not too bad for all inks. Reckon I have another 5/6 years before the cartidges need replacing again
