Comment 2 for bug 502050

I've been playing around with settings for this printer a little more, and here's a bit more detail:

Step 1. Install the printer and set the following default options:
Duplex Unit: Installed
2-sided printing: off
-> All print jobs (e.g. from Acrobat reader) default to single sided (and print single sided). User can choose to print double sided and this works.

Step 2. Modify the default settings as follows:
Duplix Unit: installed
2-sided printing: long-edge binding
-> all jobs default to (and print) double sided. If user sets 2-sided printing option to 'off', job still prints single-sided.

Step3. Modify the default settings again:
Duplix Unit: installed
2-sided printing: off
-> all jobs show default 2-sided setting = 'off', but they print double sided.

Step 4. Modify default settings again as follows:
Duplix Unit: not installed
2-sided printing: off
-> Print jobs show default setting of 2-sided = off, and print single sided. User can set duplex printing on by setting 'duplex unit' to installed and then choosing long/short edge binding.
