Hi,Michael,
Thanks for your response.
I reproduced it with Postscript printer also, and that is happened with USB port only. I think maybe USB backend won't handle error recovery well for data send failed, but I could not make sure that is USB backend issue or USB driver issue.
How do you think about it?
Thanks!
Horky
