--- Comment #4 from Dan Kegel dank@kegel.com 2008-03-08 13:25:45 --- Looks like a flow control problem. User writes:
[Problem doesn't show up with large hardware buffer in the printer.] A larger buffer than the job may not show problems. In a POS printing a invoice is a small job 1K-2K, a older printer with a small buffer (Star SP200 1K buffer) will see problems a newer printer with a large buffer (epson TM-U220 4K) seems to work must of the time, so to test I disable the hardware buffer, i tried do change the bios settings (normal, epp etc) and the parport options (irq=none, dma=none etc) to no avail, and the problem shows even in a vmware guest.
