    Color rendering and resolution are perfect. I've been trying for months to get the correct color cart for this printer. 2 other suppliers sent what they had, and got them back. This HP Deskjet 842c only recognizes the C6625AN and NH-R6625. C6625A doesn't work, contrary to what most suppliers think.

    Your ink cartridges are working out very well for me and just as good as the more expensive brands. I’m grateful for your discounts, and that you offer lower rates, as I am on a fixed income. I don’t always use my printer, but it’s nice to have your company as a great resource. Glad I found you guys - thank you so much!!
