Wrapper around the weasyprint library which allows you to print html to a pdf file. This package does not require any external software or packages to be installed in order to use weasyprint.

Getting started


NuGet Badge

dotnet add package Weasyprint.Wrapped


You might want to provide the printer class using your DI Container.

  1. Initialize
    This will unzip the needed asset, it is best done during startup procedure. The printer will check if the asset is already unzipped, so the process is only done once (or when the package is upgraded and the version changed).
await new Printer().Initialize();
  1. Print
await new Printer().Print("<html><body><h1>TEST</h1></body></html>");


This is a large package, try to limit the projects where it will be installed.

  • +-104 MB zipped resource (standalone python, gtk3 for windows and weasyprint) which will be unzipped on initialization in the same folder (for windows).
  • +-89.7 MB zipped resource (standalone python and weasyprint) which will be unzipped on initialization in the same folder (for linux).

Extra resources


Thanks to all these great repos and the guys maintaining them!!!

Create test package and run example





Create package:

cd .\src\Weasyprint.Wrapped\
dotnet pack -p:PackageVersion=0.0.25 --output nupkgs

Update the example project package version (Weasyprint.Wrapped.Example.csproj) and run the example to test it

Error in tests

The following error might be thrown when running the tests on windows:

(process:13448): GLib-GIO-WARNING **: 17:21:45.816: Unexpectedly, UWP app `Microsoft.OutlookForWindows_1.2023.1114.100_x64__8wekyb3d8bbwe' (AUMId `Microsoft.OutlookForWindows_8wekyb3d8bbwe!Microsoft.OutlookforWindows') supports 1 extensions but has no verbs

Building assets

Windows (build-on-windows.ps1 does approximately this)

$Env:PATH += ";C:\weasyprint.wrapped\standalone-win-64\gtk3\bin"
  • Install weasyprint in the standalone python
cd c:\weasyprint.wrapped\standalone-win-64\python
.\python.exe -m pip install weasyprint
.\python.exe -m weasyprint --info

Linux (build-on-linux.ps1 does approximately this)

cd c:\weasyprint.wrapped\standalone-linux-64\python\bin\
python3 -m pip install weasyprint
python3 -m weasyprint --info


  • Check PATH in python
.\python.exe -c "import os; print(*os.environ['PATH'].split(os.pathsep), sep='\n')"
