Hi,
I'm using RELENG_4 from a couple of days ago and trying to drive my
new toy - an HP Laserjet 2550L colour printer via the USB2 port on my Asus
A7V333 motherboard. The printer has PCL6 and PostScript 3 support, so I'm
using it as a PostScript printer.
It /nearly/ works. The first job to the printer prints fine (and
quickly) but the data transfer light keeps flashing and the printer will
not print anything else until a timeout passes, at which point there's a
small clunk from the printer and it will take one more job. In the
interevening period it swallows all the data sent to it but never prints
anything.
When connected to the parallel port the printer works fine, although
the data transfer light keeps flashing after the job has been sent. If I
can get the USB2 interface going properly I would be happier, even with
ECP/EPP large print jobs are slow to transfer.
The ehci bits of dmesg are:
ehci0: <EHCI (generic) USB 2.0 controller> mem 0xd5000000-0xd50000ff irq

This means that they will wait (and wait, and wait...) for the end of job character (Ctrl-D) before they think that a job is finished. This is normally included in print filters for Postscript, so if you are using a standard print filter, this probably isn't the problem. Another problem is the "data in print buffer, but I haven received a ff (new page) command / character". Typical of this problem is a flashing or lit "data" light on the printer. Some printers will then swallow data until they get their buffer emptied (new job, new page, etc.). HTH -- Regards, Torfinn Ingolfsen, Norway
