I think I asked this before, but quite a few years ago.
If you have an inkjet printer, what ink cartridges do you use?
I use my LaserJet 4M+ for most printing these days, but still have the Canon Pixma IP4000 which I got in 2005 (nearly 7 years ago ), for printing photographs and colour documents. Its ink cartridges, which I put in in 2009 finally ran out a few months ago, and I just got round to replacing them. For the last few years, I used Canon genuine cartridges and have been very happy with the quality, even if they are a bit expensive. I did for a while, use some cheap unbranded ones and thought they were no where near as good.
I remember on my old Epson Stylus Photo 750 (which I think still works), we used cheap cartridges in that for years, and I'm pretty sure the print quality deteriorated over time. Maybe if I can find some genuine cartridges at a decent price I will get the printer fired up again just for the sake of it. It was never too good at printing text I though but it was pretty good at photographs.
As for the Laser printer, the toner cartridge in that has been in since 2008.
