Re:Lexmark, the Printer Industry & cartridge c (Score 1)

I looked at HP's website for their retail prices and some information.

Your DeskJet 722c printer uses the HP 23 color cartridge. It has 30 ml of ink and has a retail price of $34.99. This is about $1.17 per milliliter of ink. (Twinpack available for $53.99, $0.90 per ml.)

The DeskJet 950c printer uses the HP 78 cartridge. The large capacity version of this cartridge has 38 ml of ink at a price of $53.99, which is $1.42 per ml. (The low-capacity 78 cartridge is $34.99 for 19 ml, for an even worse $1.84 per ml.)

HP later came out with the HP 57 ink cartridge. It is $34.99 for 17 ml of ink, a cost of $2.06 per ml. (The 57 twinpack is $62.99, $1.85 per ml.)

HP's newest color cartridge is the HP 95/97 cartridge. The 95 cartridge is $24.99 for 7 ml of ink, which is an astounding $3.57 per ml!

You can also get the HP 97 "Large" cartridge, which is $34.99 for 14 ml of ink. This comes in at $2.50 per ml. (HP 97 twinpack is $62.99, $2.25 per ml.)

Funny that a TWINPACK of the largest volume cartridge gives you 28 ml of ink, which is just UNDER what one HP 23 color cartridge gave you!
