[Pkg-cups-devel] Bug#644205: org.freedesktop.DBus.Error InvalidArgs....

[ael]

D [03/Oct/2011:23:18:17 +0100] Calling DeleteDevice(cups-HL1250)
D [03/Oct/2011:23:18:18 +0100] failed to DeleteDevice: org.freedesktop.DBus.Error.InvalidArgs:Type of message, `(s)', does not match expected type `(o)'

I notice several of these DBus errors in the log. Are they significant?

I have been experimenting with the cups installation to no avail.
I tried clearing /var/cache/cups/ which may not have been wise.

I also removed /etc/cups/printer.conf expecting cupsd to rewrite
it when I used /etc/init.d/cups restart, but that did not happen.

The system is still reporting that the printers are paused 
because (for the default printer) 
  Backend /usr/lib/cups/backend/parallel does not exist.

I did discover that the kernel that I was using when I reported was not
configured for the ppdev module, but I have now have the module
installed, and there is no improvement. Except that now "parallel"
provides more information:

# /usr/lib/cups/backend/parallel
direct parallel:/dev/lp0 "Brother HL-1250 series" "Brother HL-1250 series LPT #1" "MFG:Brother;CMD:PJL,PCL,PCLXL;MDL:HL-1250 series;CLS:PRINTER;" ""
