It seems that the LaserWriter Bridge 2.1 no longer works after installing 8.6.
With earlier versions (maybe 8.1, but definitely 8.5) the first attempt (after booting) at printing always resulted in an error. Pressing the "Try Again" button in alert informing me that there was a printing problem worked 99% of the time, or just plain old sending the print job again.
Now none of that works and the printer doesn't show up in the Chooser.
Now I see at least one company that offered a cash rebate on their LocalTalk/Ethernet bridge for printing has let it expire (end of April).
