can't get CUPS working with Xerox Phaser 6280DN

[Steve Kleene <skdeb@syrano.acb.uc.edu>]

I am failing to get CUPS working with a new Xerox Phaser 6280DN color laser
printer connected by USB.  The OS is Debian Lenny.  The printer and driver
seem to be installed OK, and I can successfully queue up print jobs from
acroread or with a command such as this:

  lpr -P Phaser_6280DN test.ps

However, the jobs get queued and don't print.  They show as pending (Pages =
Unknown).  If I try to Reprint from http://localhost:631/, I get an error
"Job #12 is not complete!".  The reprint request adds the following entries
to /var/log/cups/access_log:

  localhost - root [22/Dec/2009:11:48:30 -0500] "GET /jobs/?op=restart-job&job_id=12&job_printer_uri=/printers/Phaser_6280DN HTTP/1.1" 200 0 - -
  localhost - - [22/Dec/2009:11:48:30 -0500] "POST /jobs HTTP/1.1" 200 139 Restart-Job client-error-not-possible
  localhost - root [22/Dec/2009:11:48:30 -0500] "GET /jobs/?op=restart-job&job_id=12&job_printer_uri=/printers/Phaser_6280DN HTTP/1.1" 200 3300 - -

Here's some history.  The printer was automatically listed in printers.conf
when I connected it and turned it on.  I installed a driver provided by the
Xerox site.  It is here:

  /etc/cups/ppd/Phaser_6280DN.ppd

and shows the following:

  *PCFileName:    "FOO2LAVA.PPD"
  *Manufacturer:  "Xerox"
  *Product:       "(Phaser 6115MFP)"

http://localhost:631/printers/ shows the following:

  Description: Xerox Phaser 6280DN
  Location: (blank)
  Printer Driver: Xerox Phaser 6115MFP Foomatic/foo2lava
  Printer State: processing, accepting jobs, published.
  Device URI: usb://Xerox/Phaser%206280DN

The openprinting.org database says to use the foo2lava driver for a Xerox
Phaser 6115MFP.

I couldn't find any way to send a file directly to the USB port.
Establishing a USB connection causes these devices to appear:

  usbdev5.8_ep00
  usbdev5.8_ep01
  usbdev5.8_ep82

and lsusb shows "Bus 005 Device 008: ID 0924:3d62 Xerox".  But a test like
this:

  cat test.ps >/dev/usbdev5.8_ep00

returns "No such device or address".  A few years ago, I could test a USB
printer by copying directly to /dev/usb/lp0.

Finally, I will mention that I do not have a Windows PC handy to test the new
printer itself.  I only have a VMware XP client.  The driver installed and
displays fine, but when I send a print job it gives the blue screen of death.
I've had other problems with VMware Server 1 and USB devices.

I'd appreciate any advice on how to get this working from Debian.  Thanks.
