Re: Sorry Mr. Flaxman, but it is MY printer, not yours....
Actually, thinking of subscriptions...
I was in PC world and they were offering HP subscriptions. Something like £2.99 for 50 pages/month up to £7.99 for 300 pages a month. What kind of headcase goes for that? £96 to print 3600 pages? I suspect even genuine HP cartridges work out cheaper.
