Dependable, high quality, and no warranty issues
I prefer the HP inks for a few reasons: 1) they are the least expensive part of the printing, 2) I have used bargain inks in the past only to find that they lack the vibrance of color, don't last as long, and/or stop working due to a flaw in the compatibility chip in the cartridge, and 3) if I encounter a problem with any cartridge, HP stands behind their products and it is replaced immediately. Lastly, I'm using an HP plotter that I invested a lot of money into. I will not use an off brand ink to save a few bucks when I might actually void my warranty for the plotter. Why would I? Why would you?

What type of cartridge fits the HP Envy 6400e all in one series. Black and white and color
Thank you for your question! The HP Envy 6400e is a printer line and not an individual printer. However, the HP Envy 6455e, the currently available printer in that line, uses the HP 67 ink. That ink should be compatible with your printer and can be found at this link: https://www.hp.com/us-en/shop/sitesearch?keyword=67

How many Milliliters of ink are in one cartridge?
The HP 712 yellow ink will contain 29ML per cartridge. Thanks for your question!
Date published: 2023-05-12
is the ink waterproof
No, the HP 712 inks are not waterproof. Dye-based inks are water-resistant but not waterproof. They can run and smudge when more water is applied unless a mordant is added. However, dye-based inks can be printed on specially coated label material to make the print water-resistant.
