I’m also a fan of the HP Instant Ink scheme, I usually pay £1.99 a month for 50 pages ( any not used one month roll over to the next) but when I was sorting out mums paperwork after she went in a care home I needed to download lots of forms etc so upgraded to the next tariff to print 100 pages a month, very easy to change month by month.
I worked out that in the first year, I paid £24 on the scheme and had two sets of ink included - which would have cost almost £50 in the shops! The only additional cost is paper but I got a cracking deal of buy three reams and get two free so I bought a box and am steadily working through it. I also print a lot for my WI as I am the President and get sent flyers and forms each month by email so I’d be lost without a reliable printer.
I did have problems setting it up initially but the HP help desk was brilliant and sorted the problem very quickly and now I print from my phone, iPad and laptop anywhere in the house! When I was on a phone line with a router for broadband I had to have the printer next to the router which was in the hall so not the best location. But now I use cable, I can have the printer out of sight in my craft room.
Obviously you need to collect your printing and possibly add paper, which means walking to the printer, but I find it very useful if I’m browsing emails or Pinterest in bed to print immediately as otherwise I forget!
