OK, finally got around to trying to print on the IPF5000. Can't do it!
I am using the Photoshop Export plug-in, and the only media sources listed are "Roll Paper" (which I can't use because I don't have any roll paper, or the auto roll feed yet) and manual (which I assume is the top slot AKA "the tray"). There isn't any cassette listed! Could this be related to the GARO Status Monitor crashing on startup? Anyone else have this problem?
