It used to be that way for all HP printers. I haven't kept up with things too well, but HP makes plenty of printers with "permanent" print heads and replaceable ink tanks now (my guess is that Epson had a patent on separate ink and print-head and that is now expired). This puts more pressure on keeping the print heads in good shape for the life of the printer, but makes the replaceable parts cheaper (at least for HP?).
