Wkhtmltopdf

The version of wkhtmltopdf available in Debian/Ubuntu repositories does not support headers and footers (requires patched QT version). As there is no official release for Debian Jessie in the official downloads page, you can find ours on http://nightly.odoo.com/extra/.

• 0.12.0(.*): not recommended, minimal supported version as of Odoo 8. Several known issues fixed in 0.12.1.
• 0.12.1(.*): recommended version - In production on Odoo Online (.deb for Debian jessie). Known problems:
  • Some rare crashes during layout of multi-page tables (workaround: play with margins and/or dpi settings: 96, 100, 110dpi). Appears to be fixed in 0.12.2, but this version has worse problems.
  • Known exponential memory usage and file descriptors usage when rendering documents with many pages (500+). Workaround: increase fd limit with ulimit, remove header/footers (internal layout). Experimental dirty fix: split the long table in smaller chunks and use pyPdf to merge the pages.
• 0.12.2(.*): not recommended. Known problems:
  • --dpi parameter broken, causes ugly/broken layout (using zoom could be a partial workaround but requires complex ratio computations on win32 due to default dpi)
  • fails to execute external JS file in header/footer (Supposedly fixed in 0.12.3)
• 0.12.3(.*): not released yet
  • --dpi parameter still broken, causes ugly/broken layout
