[Bug 385797] Re: Generic text-only printer does not work
* debian/local/text.convs: Turn all text input formats to text/plain at a high cost, so that the text-only printer (which accepts only text/plain) accepts them (LP: #385797). I don't understand what's so costly about dumping text input straight to the printer. There shouldn't be anything required to do that. If we're whitelisting things, I think that there must be a better way. For starters, we could identify source code correctly, with a MIME type of text/x-csource instead of application/x-csource. The latter implies that the source code may or may not be binary, when it isn't, it's source code, which _is_ plain text, not something that is costly to turn _into_ plain text. Seems like a decent stop-gap for the time being, but maybe another bug should be opened to detect formats correctly according to their major type (text, image, application, etc.)? It also looks like the problem might be that CUPS wants to turn it into PDF as per /usr/share/cups/mime/texttopdf.convs, which contains: Ubuntu Jaunty:[0-17/10295-0]:mime cat texttopdf.convs application/x-cshellapplication/pdf 0 texttopdf application/x-csource application/pdf 0 texttopdf application/x-perl application/pdf 0 texttopdf application/x-shell application/pdf 0 texttopdf text/plain application/pdf 0 texttopdf text/html application/pdf 0 texttopdf I don't see a PPD for my C500 printer (the one that is plain-text only). I have one for my e250dn, though, in the /etc/cups directory. -- Generic text-only printer does not work https://bugs.launchpad.net/bugs/385797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The high cost factors I have set in my new rules as these rules are only a fallback. Conversion rules taking into account the particular type of text should be preferred (they have a lower cost factor), to assure that things like prettyprint work correctly. Due to the high cost factor my rules will only be used if there is no way to get a filter path when using the particular types of text directly. -- Generic text-only printer does not work https://bugs.launchpad.net/bugs/385797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ah, so it's a virtual cost, like one can set in routing tables.

[Bug 385797] Re: Generic text-only printer does not work
Tim, can you have a look at your Generic Text-Only printer? The textonly CUPS filter does not touch paper sizes anywhere and the PPD file has only a Letter paper size, no A4, nothing else. The PPD file should also have a cupsFilter lines like *cupsFilter:text/* 0 textonly *cupsFilter:application/x-cshell 0 textonly *cupsFilter:application/x-perl 0 textonly *cupsFilter:application/x-shell 0 textonly *cupsFilter:application/x-csource 0 textonly instead of *cupsFilter:text/plain 0 textonly so that all text formats defined in /etc/cups/mime.types get supported. Another solution for the text-only printer to recognize the additional text formats would be adding the following conversion rules (for example in /usr/share/cups/mime/text.convs): application/x-cshell text/plain 100 - application/x-csource text/plain 100 - application/x-perl text/plain 100 - application/x-shell text/plain 100 - text/html text/plain 100 - text/css text/plain 100 - This makes all text formats falling back to text/plain if there is no filter chain accepting the text formats themselves. ** Changed in: cups (Ubuntu) Importance: Undecided = Medium ** Changed in: cups (Ubuntu) Status: New = Triaged -- Generic text-only printer does not work https://bugs.launchpad.net/bugs/385797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 385797] Re: Generic text-only printer does not work
Added the mentioned /usr/share/cups/mime/text.convs file to the BZR repository of CUPS at Debian. So our next CUPS package will have this bug fixed. ** Changed in: cups (Ubuntu) Status: Triaged = Fix Committed -- Generic text-only printer does not work https://bugs.launchpad.net/bugs/385797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 385797] Re: Generic text-only printer does not work
This bug was fixed in the package cups - 1.3.10-3 --- cups (1.3.10-3) unstable; urgency=low [ Till Kamppeter ] * debian/cups.install, debian/rules: Move added *.convs and *.types files to /usr/share/cups/mime/ so that they are not considered config files by dpkg. * debian/local/text.convs: Turn all text input formats to text/plain at a high cost, so that the text-only printer (which accepts only text/plain) accepts them (LP: #385797). * debian/rules: Switch the pdftops filter back to Poppler, as Ghostscript has a lot of problems in generating PostScript (LP: #382379). * debian/patches/poppler-based-pdftops-fixes.dpatch: Fixes for the pdftops filter in Poppler mode: Do not emit PostScript level 3 as it Poppler's PostScript level 3 output is not compatible with HP's PostScript printers (LP: #277404); Added support for the new -origpagesizes option of Poppler's pdftops, so that documents with pages of different sizes get correctly printed (LP: #310575). * debian/filters/pstopdf: Do not call Ghostscript with asymmetric resolutions (like 1200x600 dpi), as it leads to problems with images in some cases. See http://bugs.ghostscript.com/show_bug.cgi?id=690504. * debian/local/filters/pdf-filters/pdftopdf/P2PObject.h, debian/local/filters/pdf-filters/pdftopdf/P2POutput.cxx: Fixed infinite loop which occured for some PDF files (LP: #382880). * debian/filters/pstopdf: Make it also correctly working if PaperDimension and ImageableArea entries in the PPD have no translation strings. Thanks to Koji Otani to find the bug. * debian/local/filters/pdf-filters/pdftoopvp/, debian/local/filters/pdf-filters/README, debian/local/filters/pdf-filters/addtocups, debian/local/filters/pdf-filters/removefromcups, debian/local/filters/pdf-filters/config-scripts/cups-pdf-filters.m4: Added pdftoopvp CUPS filter as part of the PDF filter add-on. * debian/cups.install: Make /etc/fonts/conf.d/99pdftoopvp.conf of pdftoopvp be installed as part of the cups package * debian/control: Added build dependencies needed by pdftoopvp: liblcms1-dev, libfreetype6-dev, libfontconfig1-dev * debian/control: Moved dependency on cups-client to Depends:, as cups-client is needed by the post-install script for the update of the PPDs of existing print queues. * debian/cups.postinst: Case-insensitive check for model names when updating PPDs of already existing print queues. [ Martin Pitt ] * Add gnutls-pkgconfig.dpatch: Use pkg-config gnutls instead of deprecated libgnutls-config. (Closes: #529903) * Bump Standards-Version to 3.8.1 (no changes necessary). * debian/control: Point Vcs-Browser: to bzr.d.o. loggerhead, and use http:// URL for Vcs-Bzr. * debian/control: Drop ghostscript build dependency again, pdftops filter uses poppler again. Also Drop alternative xpdf-utils build dependency, since configure now checks for poppler's pdftops capabilities. * debian/control, debian/rules: Do a build-time check if pdftops supports -origpagesizes, and dynamically set the poppler-utils dependency. This is a hack until https://bugs.freedesktop.org/show_bug.cgi?id=19777 makes it into Debian. * debian/cups.install, debian/local/filters/pdf-filters/addtocups: Disable new pdftoopvp filter for now, since sid does not yet have poppler 0.11. Lower libpoppler-dev build dependency again. -- Martin Pitt martin.p...@ubuntu.com Thu, 11 Jun 2009 12:19:33 +0200 ** Changed in: cups (Ubuntu) Status: Fix Committed = Fix Released ** Bug watch added: Ghostscript (AFPL) Bugzilla #690504 http://bugs.ghostscript.com/show_bug.cgi?id=690504 ** Bug watch added: freedesktop.org Bugzilla #19777 https://bugs.freedesktop.org/show_bug.cgi?id=19777 -- Generic text-only printer does not work https://bugs.launchpad.net/bugs/385797 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
