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.
