The suggested maximum monthly duty cycle for the printer is 1000 pages.
And that isnt the only thing different.
The amount of ink that a tank unit can contain is a lot more than a cartridge can.

The ink tank on HP Ink Tank 319 is an external part that contains four ink tanks.
Each of them has a maximum and minimum line.
When the ink level almost reaches the minimum line, the ink tank should be refilled.

When refilling a tank, the ink level should not exceed the maximum line.
HP successfully developed an ink refilling system that allows the tank much easier to refill.
It is so easy to refill that it is unlikely for the ink to spill unless done on purpose.

Auto duplex printing is not supported.
Wireless connectivity doesnt exist.
Automatic document feeder is not available.
The tests were based on the ISO standard.
HP Ink Tank 319 has a power saving feature.
If the machine is not used for five minutes, it will enter the sleep mode automatically.

After it is turned off, the only way to turn it on is by pressing the power button.
A single Hi-Speed USB 2.0 is available for the connection.
The recommended monthly volume for the printer is up to 800 pages.
