What protocol are you using? If the printers are suppossed to get addresses as they power up you need to enable port fast.
The oversized packet issue may be related. But do these printers always fail or just when fragmented packets come at them? Try pinging the pc in the same vlan with the large packets. If it fails then you need to track down where the ip fragments are being dropped.
I have had a similar problem to yours. I got rid of it by reloading the IOS to the problem switches, copied from a working switch. Also set speed/duplex at switch and printer. Been OK for 14 months now. Hope this helps.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
