Rated 5 out of 5 by F/V Nocona from Hp Ink for DesignJet T 650 Trouble-free, long lasting ink cartridge.
Date published: 2025-06-15
Rated 1 out of 5 by T250 large format from Return to sender Never received any of the orders. Unable to ship to address. No notification. Two hours with customer service. Finally found that packages have been returned to their warehouse. This is not the way things used to work with them. Previously orders were delivered within 3 to 4 days as promised. Things have changed with HP. Very frustrated. Worthless time vampire. Be careful about your shipping preferences. Refund period is future day at least a week out from when you contact them and say that you never received your order. Got off the phone with them and ordered from Amazon and had the materials in three days.

Rated 5 out of 5 by johncruet48 from Fine Accessory to the T230 Printer The HP DesignJet T230 shipped with "starter cartridges." That being said, I anticipate that this cartridge will give comparable performance. It is to HP's credit that the Black 712 has more capacity than the color cartridges since my practice prints principally black line prints with this printer. My former HP DesignJet 111 was conservative in its consumption of ink; thus far it appears the HP DesignJet T230 will follow suit.
