Context
Using Debian 6.04 "Squeeze" as POS station.

There are two printers installed: Network printer and a receipt printer

It absolutely must be able to print by default to the receipt printer on a certain website though the system default is a network printer. In Debian ...it doesn't.

Problem
I've set up XP, 7, Ubuntu and even Mac OSX this way, so I'm no stranger to setting Firefox up this way ...same Iceweasel/Firefox settings ...complete fail. Always uses system default no matter what the settings, or, which printer you print from.

To get this to work on other systems you do this:

1. Print a page in Firefox using desired printer.
2. Ensure print.save_settings is true.
3. Firefox remembers last printer used
4. Set print.always_print_silent = true

The end. This works on every OS I've set up ....except Firefox and Iceweasel in Debian.

My only recourse seems to be to set the receipt printer as default or go back to bloaty Ubuntu/Mint ...etc.
