eggcups (and libgnomecups) for 2.12
by Colin Walters

Rate this Message:
Hi,
Looking at the schedule I thought I'd missed the time period left for new modules, but looking again it appears we still have a small amount of time. I'd like to propose eggcups for 2.12. For more information about eggcups, see: http://mail.gnome.org/archives/gnome-announce-list/2005-June/msg00033.html And particularly: http://mail.gnome.org/archives/desktop-devel-list/2004-July/msg00126.html Getting eggcups in 2.12 would also mean libgnomecups (presumably in the Desktop platform). Does that sound reasonable? eggcups (and the revamped libgnomeprint print dialog) have undergone a lot of testing in Fedora, and I think they're ready for inclusion in GNOME. _______________________________________________ gnome-print-list mailing list gnome-print-list@... http://mail.gnome.org/mailman/listinfo/gnome-print-list |

Basically you print something, an icon appears, it greys out when all your jobs are done. You can click on it to find out their status.

I'm not sure how to answer that since I don't know exactly what you're referring to by "gnome-print".

As far as I can see from that bug the reporter is complaining about two things: 1) Lots of entries in the CUPS access log: well, the default CUPS access log is verbose, simply tune it down. 2) The polling continuing after the print dialog has been closed: that's definitely a bug. I can't seem to reproduce it here. In any case these are bugs, not reasons to revert important end user visible functionality. _______________________________________________ gnome-print-list mailing list gnome-print-list@... http://mail.gnome.org/mailman/listinfo/gnome-print-list |

We did some work to make most operations like retrieving printer status (from remote printers) asynchronous, but certainly some things are synchronous simply because we knew they were talking to the local cupsd and thus should be reliable. I don't think it would be impossible to make those operations asynchronous, but also think it would be far from trivial. Why wouldn't one have a local cupsd? > So the "important end user visible functionality" in act makes this > library useless to many users. Users who don't have a local cupsd?

Everything worked fine for us before these changes of making things asynchronous. > > Why wouldn't one have a local cupsd? Good question. We have local cups daemons. Since the whole asynchronous stuff apparently got included to avoid delays when talking with a non-responsive remote cups daemon, I assume there are some people somewhere that are trying to avoid having a local cups daemon. > > > So the "important end user visible functionality" in act makes this > > library useless to many users. > > Users who don't have a local cupsd? Do I understand the scope of the > issue here correctly? No. Users who _do_have_ local daemons that talk with several remote daemons that administer the printers. Remember in this configuration, the ppd files reside with the remote cups daemon. the whole pont of broadcasting printers is that we do not have to configure those printers on each client. The local cupsd daemons just pick up the printers from the broadcasts. Andreas > -- Andreas J.

The local cups daemon should be able to respond without talking to a remote printer. b) submitting a print job to the local daemon. Again it shuold place the job in its local queue and only then try to talk to the remote daemon. It does the latter asynchronously anyways. c) loading ppd files. Yes they need to be retrieved from the remote daemon, but this should happen only when the printer is selected in the dialog. So in the sychronous way that will cause a delay if the user wants to print to a misconfigured or down printer and that printer is still known to the local daemon, which in a broadcast situation will only happen for a short period of time after the printer went down.

And while it used to work great for us, we now have to recompile libgnomecups to make it work in any acceptable way and what are we gaining? Little numbers in the print dialog that says that there are a few print jobs not yet sent to the physical printer. A bad trade as far as I am concerned. Andreas > -- Andreas J.
