I use and saw people using hp printers for the last 23 years. Previously the printers had good ink reservoir in the cartridges, but now they have reduced the size of the ink content. The ink content in ink advantage printers is good but still the cartridges are very delicate to handle.
One more unique feature they have added works disadvantageous to people having same two printers of similar cartridges. Suppose someone have two printers both having same 678 cartridges but made the hp ink protect feature on in the settings and if the cartridges swap two printers then the cartridges will not work on alternate printers as they are protected to work only in the same printer in which it was installed. I saw the 678 cartridges have the most failure rate while refilling as everyone knows Indian soho segment will never buy new cartridge every time.
So think before buying an hp printer with 678 cartridge as was the 818 cartridge A FEW YEARS BACK.
