Yes interesting reading. It gives a good explanation of the differences between Epsons and most other brands.
It also brings back memories to me. My first inkjet printer was a Canon BJ-10ex or BJ-10sx, very similar to the BJ-10v Lite in the upper right corner. It was a monochrome B/W printer and the BC-02 cartridge was the first I refilled. The printer was a portable model, and a battery pack was an optional extra. It had no sheet feeder, so paper was fed one sheet a time, in typewriter style. For home use a special stand with sheet feeder was an optional extra. I think the printer was introduced in the days of Windows 95 and DOS was still widely used. Note the dip switches which allowed change of character pitch and other settings when used in DOS and gave the possibility of emulating a matrix printer known by DOS, like Centronics or IBM Proprinter IIRC.
