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, you can find ours on http://nightly.odoo.com/extra/.

• 0.12.0(.*): not recommended - why?
• 0.12.1(.*): recommended version (currently used on Odoo Online) - some known crashes during layout of multi-page tables. Note: not in debian before jessie/ubuntu before 15.10, available in nightly.odoo.com
• 0.12.2(.*): not recommended
  • --dpi parameter broken, causes ugly/broken layout (supposedly fixed in 0.12.3)
  • fails to execute external JS file in header/footer, (supposedly fixed in 0.12.3)
