LWN put my printing summit notes atop the development news section. Whee!
Robert sent me some additions for the vendor relations discussion part which I'll incorporate at some point.
Lexmark has asked me to review and comment on a printer. This is a fine thing, all in all, but they wish to use my comments in their ads. It seems appropriate for me to charge them for that privilege; they are evidently pondering that idea.
Mulad pondered the whole printing thing a bit:
I mean, I don't want to define a new printer in /etc/printcap just to be able to run at a different resolution or to print in color or whatever. This is something that has been missing for a long time. Of course, what's the best way to do this? You don't want every program that wants to print to be dependent upon a particular graphical widget...So the approach currently used is to provide a defined interface between the spooler and print submission program, which includes data about the possible options. Currently, this interface is done in two parts: typically PPD files document the options, and job submission programs magically know how to specify options to the spooler (arguably, this is OK, since there are only 6 or so spoolers in the world). This approach is sligthly inelegant and not commonly used, but all the bits are there, so it's up to you to install it. Read the HOWTO. (Or rather, read the not-yet-published version of the HOWTO that has more data on this stuff).
I don't want more printers to be using proprietary languages...device manufacturers don't know how to make a `driver' for Ghostscript...None of us like proprietary languges. Truth be told, however, most proprietary languages are little more than a few setup bytes and a compressed stream of bits indicating how to fire the jets. At the summit we clarified the needs of free software; since all the magic is in the dithering, and we can already do that, we may now see some vendors document the jet-firing information we need. As for Ghostscript, it does indeed have a collection of awkwardnesses that will probably be addressed in future versions. There's a sourceforge project for that; join and help.
I wonder if there are yet any programs for reading the status of my Epson Stylus Color 640. I'd kind of like to know how much ink is left.Yes. Basic tools for that sort of thing are included with recent versions of the Gimp print plugin (aka the "stp" driver). It lives on SourceForge.
Sigh. I've really got to get around to some more work on the database and HOWTO...
My father in law is visiting; we're planning to eat out for the next five dozen meals. Urgh.
Yesterday I accidentally released a two foot snake in the locker room at the gym. Oops. Apparently he crawled into my bag when it was stored in the basement, and I never noticed until I unpacked to get dressed. Fortunately 3Com has a staff of comparatively expendable security guards useful for snake trapping and the like. Kelley won't go into the basement anymore.
