I have an HP Photosmart printer but recently I cannot get compatible cartridges to work in it. I know the printer is working so it must be the cartridge that is causing the trouble. I bought the cartridges from a local supplier with whom I have been dealing for years and they offered me some tips but none have worked, even though I have used these same inks for years with no trouble. I would purchase from you if I was assured that they would work. I live in the Irish Republic so returning the cartridges would be expensive if they were unsuccessful. Thanks, Helen.
