wkhtmltopdf 是用C实现的生成pdf的开源软件。可以基于网址或html生成对应的PDF文件。 对OSX, linux, windows平台都提供了对应的支持。
snappy是一个对wkhtmltopdf封装的类库，使用非常简单。
而这里介绍的 laravel-snappy 则又是对snappy的封装，只不过方便集成到Laravel框架中。
在使用 laravel-snappy 之前我建议先浏览下 wkhtmltopdf官方文档 wkhtmltopdf下载后之后就是一个bin二进制文件，提供了非常多的参数。
这里介绍下怎么在Laravel6中使用laravel-snappy并生成pdf文件
bash
# 下载安装包
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.
bionic_amd64.deb
# 安装
sudo dpkg -i wkhtmltox_0.12.6-1.bionic_amd64.deb
# 如果报错，如缺少依赖，可以执行下面这个
sudo apt-get -f install
# 检查是否安装成功
which wkhtmltopdf
# 输出
/usr/local/bin/wkhtmltopdf
which wkhtmltoimage
# 输出
/usr/local/bin/wkhtmltoimage按照 laravel-snappy 教程，添加Facade，生成config/snappy.php
新建resources/views/pos/receipt-pdf.blade.php模板, 这里面有一些变量需要Controller传给视图，需要注意字体和图片的引用。
