I am running OS 8.6 and I am amazed that MORE will even launch. I have heard of glitches related to MORE 3.1 and 8.6. Anyone report specific problems?

I've been using MORE since the beginning and it has kept up with changing systems and hardware--most recently 8.5 on a Performa 6360 printing on an Apple SW2500. Now, having just taken a "great leap forward" in hardware and software, I'm afraid I've met a brick wall: OS 8.6 running on a blue and white trying unsuccessfully to print on a Epson Stylus Color 1520 connected via a USB/parallel "smart" adapter.
MORE 3.1.1 crashes and printing alternates between perfectly formed text and tiny, miniature letters on the same page.
Does anyone have a clue about the secret of using "Old Faithful" on a new machine with a new system and a new printer? I'd hate to leap forward only to slide haplessly back. David Dunn
