Do you have backups of the /etc/cups/ dir? If it worked on the acer it should work everywhere. Often I just copy /etc/cups/* files from one systems to the next, rather than deal with that ever_changing cups interface. Also, brother printers, like most, work better in a linux/unix centric network when they are ethernet connected. If you have your printers plugged into ethernet, then you can connect to them (via ethernet) by just typing in the ip address of the printer into your web browser. That makes checking the embedded printer configuration much simpler. hth, James

Oxford is known as the 'the reference' for unabridged dictionaries in English (at least this is what some psychotic professors tortured us with, in English 101/102 some decades ago; leather helmets, dinosaurs etc).. ymmv. For meanings and etymology, the OED is the gold standard, but we're just talking about spellchecking dictionaries here. The Oxford spelling is *not* the spelling used by most of the UK. It's the official spelling of the Oxford University Press and some academic journals, such as /The Lancet/, and people writing for those publications need it. Most Oxford dons don't use the Oxford spelling. IOW, only people who have to write according to style guides which explicitly specify Oxford spelling need an Oxford spellchecking dictionary. I'm interpreting the feedback from you and Joost to mean yes we want a good UK spelling dictionary, which you'll get. If it really is *Oxford* spelling one of you needs, I need to hear a more specific plea (e.g., I write for The Lancet/). My mother has a Ph.D. in English Lit, and there was always a concise OED around my house when I was growing up, but she was unaware of the Oxford spelling until I asked her about it recently. The main difference between standard UK spelling and Oxford spelling is that Oxford spelling uses -ize endings (criticize, optimize) whereas standard UK spelling uses -ise. Using Oxford will make most readers think you're using American spelling, since Americans use -ize. I hope it is available system wide for a variety of apps? Yes, these are system dictionaries. `equery d hunspell aspell enchant` will probably show you most of the things on your system that use these dictionaries. (I don't know what GNOME uses, but it probably depends on either hunspell or aspell.)

Using Oxford will make most readers think you're using American spelling, since Americans use -ize. Yes, and I've never understood that. The -ise version is true to its French origins (remember 1066?), while as far as I can see the -ize version has no precedent. It also doesn't help with knowing which ending to use in a particular case, so I've no idea why they've adopted it. Moreover, Oxford English insists on that egregious comma before nearly every and, which is just stupid. It causes as many problems as it avoids, and it's deadly to the flow of the sentence. I once argued about it with an American contributor to an e-mail list, and was told it's a matter of style. No. Wrong. It's just slavish obedience of an arbitrary rule which cannot be justified in any rational way. Just consider: and is equivalent to a comma in most cases; it's how a child starts out until it learns something more sophisticated. So pairing the two leaves us with nonsense. Just my two penn'orth. -- Rgds Peter

This is unknown to me; but you might find help if you get sstv audio signals parsed out of your serial line signal, if I am to speculate what you are really after? You may need a spectrum analyzer to identify and isolate the audio signal since the signal is a superposition (hybrid) signal. It might be best to filter the audio signal out in the Rf domain, as opposed to it's digital derivative signal. http://users.belgacom.net/hamradio/index.htm under software he has rx-sstv for windoz. Get it working under doz and then hunt for a linux setup, using windows to verify it all works (hardware wise) first, is one possible path. Also : http://www.dxatlas.com/SstvTools/ and in portage (just to be complete) media-radio/qsstv Also verify the chipsets used (dongle?) and their reliability at various frequencies. Those chipssets that are wideband, are always problematic, imho Most of the crap (dongles) floating around are not very good. Me, I'd go to the trouble to find a new chipset, including filters and LNAs (low noise amplifiers) to build a decoder box. You could probably sell them. If you go that route, drop to me privately.
