Print job not printing

[tong]

Hi,

When I issue a printing job, it will stay in the print queue forever without
being printed:

  $ lpc status; lpq -a
  epson_cx1500:
	  printer is on device 'usb' speed -1
	  queuing is enabled
	  printing is enabled
	  1 entries
	  daemon present
  Rank    Owner   Job     File(s)                         Total Size
  active  tong    12      file.test.black.ps              100352 bytes

I checked the /var/log/cups/error_log, but there is no error message shown
after issuing the print job, when the LogLevel is warn. What could be wrong?

Here is my configured printer:

	epson_cx1500
	Description: Epson Stylus CX1500
	Location: USB Printer
	Make and Model: EPSON Stylus Color Series CUPS v1.2
	Printer State: idle, accepting jobs, published.
	Device URI: usb://EPSON/Stylus%20CX1500

And here is the list of my packages installed:

	ii cupsys_1.2.3-1
	ii cupsys-bsd_1.2.3-1
	ii cupsys-client_1.2.3-1
	ii cupsys-common_1.2.3-1
	ii cupsys-driver-gutenprint_5.0.0-2
	ii foomatic-db_20060822-1
	ii foomatic-db-engine_3.0.2-20060712-1
	ii foomatic-db-gimp-print_5.0.0-2
	ii foomatic-db-gutenprint_5.0.0-2
	ii foomatic-filters_3.0.2-20060712-3
	ii gimp_2.2.13-1
	ii gimp-data_2.2.13-1
	ii gs-esp_8.15.2.dfsg.1-2
	ii libcupsys2_1.2.3-1
	ii libgimp2.0_2.2.13-1

thanks

PS: Here is info when LogLevel is info:

I've also generated info when LogLevel is debug, but it is too much to include here, please tell me what to look for.

thanks
