Cartridges have cost me a small fortune over the years and I have 2 printers. One old Epson SX415 does printing copying, scanning etc and has 4 colour cartridges and I use that machine for general day to day stuff. The second printer is an Epson R2880 that I bought for my photography hobby, which lapsed when I got into woodworking. Both machines have always had original ink. You know, the one's that cost the most, but they do produce the best images. The R2880 has never been switched off, unless the electricity has been cut and the reason for that is every time you switch off and start up again, you use a lot of additional ink.
With any new printer, if you use refil/secondary ink or fill yourself, it will invalidate the guarantee, so particularly with the larger printer (up to A3) that could be costly. Both machines are several years old but fortunately I have never had a problem with either ........ only the ongoing cost.
