Phenomenon:
After installing the driver (such as Lenovo LJ6700DN PS) via USB protocol, it can be printed at the first time, but after the second or multiple times, the job will be canceled.
Comment:
1.Wait a few minutes and the job still won't be printed.
2.After unplugging in and plugging in the USB cable, the job can be printed
3.The problem does not occur via network printing.
4.The problem does not occur viai network.
5.Other systems (such as Windows, Mac OS) do not have this problem.
Our analysis:
1.We think that part of the data was lost via USB transmission
2.In CUPS ErrorLog, the job has been delivered completely.
(refer to error_log->[Job 313])

I [21/Jul/2022:15:21:25 +0800] [Job 313] Job completed.
3.However, I found an error on USB Request Block (URB) with Wireshark on Ubuntu 18.04
[Error: undefined; Off fendingCommand: BPdict Flushing: rest of job (to end of file) will be ignored] appeared at [URB BULK IN]
(refer to usb2.pcapng, snapshot.pn)
4.We extracted the accepted data on the printer side, the data is really lost.
(refer to prt00016.prn,
prt00013.prn is the data of normal print)
