Walter, firefox doesn't use gtk20 (except for Adobe Flash plugin) but the patch applies against both gtk20 and gtk30. Is it legal to cite two port names in the title of the bug? The problem (and the patch) apply to both gtk2 and gtk3. No problem (was my error with the title). I had written a patch, that I had forgotten, that looks similar to yours. It has a few differences. I am not the best with GTK code, so I have no idea which is correct between your patch or mine in relation to the backend and is-virtual settings. I also include accepts-ps in the function call as the lpr filter I am using handles both. Created attachment 196976 [details]
Alternate patch to fix GTK
I know less about GTK probably than anyone else on the project, so someone else should probably choose between these two patches. But the other backends don't specify "accepts-ps", so I assumed it was the default. Also, I wrote "GTK_PRINT_BACKEND (backend)" simply because that looked similar to what I saw in the other backends. But it does seem to me like a very good idea to incorporate one of these patches. Have you tried to submit the patch/rationale upstream? gnome@ (downstream) is understaffed and, probably, doesn't have enough expertise to review. Offhand, I wouldn't know how to do that ... I created an account on Gnome's GitLab server and created an issue for this: https://gitlab.gnome.org/GNOME/gtk/issues/1385 I created a pull request in the Gnome repo. It was marked for GTK4. https://gitlab.gnome.org/GNOME/gtk/merge_requests/418 Ping! There are more people who are missing the LPR printing capability in Firefox! GIMP from ports still can "Print to LPR", I double-checked 10 minutes ago. And yes, ghostscript now accepts PDF input just find, so you can configure a "ps" printer and print PDFs to it. This is what I've done. I must admit to having forgotten about this since I have been running happily with the patch I submitted upstream in September 2018. It should hopefully go into GTK4, but I have not followed what the status of that is. Also, we would have to wait until Firefox moves to GTK4. I think it should be added to ports as patch since it may be quite awhile before we see it in the applications we use. Unless, someone has push upstream to get it into GTK3. Lacking any pull with the upstream project, I've been hoping one or the other of these patches would be adopted by FreeBSD for the port since I submitted the bug. (In reply to Sean Farley from comment #13) > I have been running happily with the patch I submitted upstream in September 2018. Does it still apply cleanly to current www/firefox ? Anyway, I'd hate to build firefox locally, it's too resource- and time-consuming. Could we ask the port maintainer to add this patch to the FreeBSD ports tree? I see no harm in it.

(In reply to Victor Sudakov from comment #15) > Does it still apply cleanly to current www/firefox ? There're no patches against www/firefox in this bug. Revert from https://lists.freebsd.org/pipermail/freebsd-gecko/2018-May/008327.html doesn't apply due to high code churn uptream. The 2018-09-03 patch still applies cleanly to gtk2-2.24.32 and gtk3-3.24.10_1. The PR was merged on October 7th, 2020 to the GNOME gtk master with a GTK4 tag: https://gitlab.gnome.org/GNOME/gtk/-/commit/668868fb1f5c698abba764b24379a3fc4c405abe It seems to me we can now close this as fixed. Any objections? (In reply to george from comment #20) Let's wait for the new Firefox package (with lpr printing support) appear in the official FreeBSD package repo, and then we can close the PR. (In reply to Victor Sudakov from comment #21) I see two options: - Wait until gtk3 (and gtk2) are removed from the ports tree. - Take the patch merged into gtk4 and add it to the gtk2 and gtk3 ports. Since the first option will most probably take years to happen, I think the second option is the best choice. As of gtk v3.24.24, the pull request is in the library. Changelog: https://gitlab.gnome.org/GNOME/gtk/-/compare/3.24.23...3.24.24 Commit to v3.24.24: https://gitlab.gnome.org/GNOME/gtk/-/commit/8d5357ee (In reply to Sean Farley from comment #23) Moin moin Gtk has been updated to 3.24.24 in r557252 -- and with the next quarterly being half a month away, can we consider this resolved? mfg Tobias (In reply to Tobias C. Berner from comment #24) For x11-toolkits/gtk30, this should be considered fixed. Firefox offers "Print to LPR" in the system dialog. A patch may be considered needed for x11-toolkits/gtk20, but Firefox no longer uses that port. It looks like everyone feels this has been fixed upstream and subsequently updated within ports, therefore, closing this bug. |
Created attachment 196805 [details] Patch to tell GTK that lpr accepts PDF output The LPR backend for GTK asserts that "lpr" cannot accept PDF files. Granted, you can't tell in general whether lpr in a given situation will be able to print a PDF or not, but declaring that it can't is needlessly restrictive. The attached patch (works for both GTK2 and GTK3) adds the "accepts-pdf" property to the lpr backend and fixes the problem. This patch is suggested as an alternative to the patch from the freebsd-gecko email thread "firefox-60.0_2,1 missing 'Print to LPR'", from May 13, 2018, which circumvents the problem by generating PostScript output instead of PDF. Fixing the problem in GTK means that other users of GTK won't have to create parallel workarounds.
