Hi, Just stumbled accross this thread as i have been plagued by the same problem with a CLP 600 for a couple of months!
tried everything suggested here without success and was contemplating using it as a crash test dummy from the 3rd floor window when i thought i'd give it one last attempt!
2Hrs later i may have a config that works!!!!
print processor - winprint RAW
Disable bi-directional comm
configure LAN port settings as LPR to queue 'lpt1'
byte counting enabled
snmp disabled
advanced printing features disabled
set spool setting to - start printing after last page spooled
Printed a flash website 150 times without it falling over! It previously failed every time!
Fingers Crossed!!!
