My friend just bought a HP #74 ink cartridge for her printer only to realize later that she needed a #92. Unfortunately, she got it at a circuit city that is going out of business and she cannot exchange or return it.
I know #74 ink carts use the same ink as #92 and I am pretty sure they are the same size/shape. I am not sure however if the electrical connections at the back of the carts are the same or if the printer will simply reject them.
Personally I have a HP printer which says to only use #94 black ink carts. But I have been using a #92's with no problems.
Thanks in advance
