I ask because I just tried it. I've done a number of profiles with my Spyder3Print SR for various papers, and while the initial profile is never quite right, it's looks like it's in the ballpark. The S3P profile editor gets me the rest of the way there.
I've read elsewhere that the Easy 43 patch version of i1Match print profiling is marginal at best. I decided to try it (with my i1Pro). I let the 43 patch test print on Canon Photo Paper Pro Semi Gloss dry for 48 hours before reading. I just softproofed an image in Photoshop with that profile and it has a horrible sickly green cast. Intent was Perceptual, and Simulate Paper White was selected. Doesn't look much different in Relative Colorimetric. I did get the proper "single beep" after each row was strip scanned.
I expected it to be not so accurate, but this was just unsightly. Display of course was just calibrated with i1Match and my i1Pro. Monitor is a Sony GDM-FW900.
(My printer profiling excursions go back to the Pantone ProfilerPLUS days. I'm no expert but also not a noob in this area.)
