I can't believe I STILL haven't ordered and tested any yet, but there is a second mix of BubbleJetSet on the market now formulated especially for Hewlett Packard printers. All their other products perform as advertised, and CJ Jenkins has always been very honest about the differing performance of ink formulas with BJS, so i expect to be pleased.
Unless somebody tests and reports first (hint, hint, HINT!!!) i'll let you know how it goes when i finally get around to it.
