Should the continuous ink supply cartridge of Epson inkjet printer be flush with the printer or with the cable car?

This is an interesting question. It doesn't really make much difference. Practice is a communication. Do you think it is definitely not possible to put the external bottle high, parallel to the machine base and parallel to the car? You are too entangled. Epson's ink cartridges are all equipped with constant pressure cutting. As long as the pressure in the ink cartridge is not high, it is controlled by constant pressure cutting (the ink cartridge was originally a sponge ink cartridge, which was invented by a manufacturer in China, but patented by Epson). Just don't be taller than the printer. It doesn't matter whether it is on the same level as your printer or car. Also, Canon's ink cartridges are sponge-type ink cartridges, and it is best to put them at the same height as the car.
