树莓派+打印机=局域网打印机，电脑手机平板无需安装任何软件驱动即可使用打印机（填坑记录）

因为需要使用打印机的地方非常多，我专门买了一个打印机佳能Cannon MG3680,按照网上的教程配置想打造一个局域网打印机，但是过程却极其艰辛，所以今天来说说树莓派安装以及配置打印机的那些坑，同时我还录了个视频，大家可以看一下。
以防权限不够，转为root

sudo -i

更新软件，保持最新的状态

sudo apt-get update
sudo apt-get upgrade

安装CUPS及相关依赖

sudo apt-get install cups cups-pdf cups-bsd

将pi用户添加到打印机中

sudo usermod -a -G lpadmin pi
sudo systemctl restart cups

允许所有流量访问CUPS,注意的是这步可以不用做，记得重启，因为可以通过CUPS的图形界面配置，具体可观看视频配置。

sudo cupsctl --remote-any

安装SAMBA,如果不要NAS也可不使用，如果安装的话，设备就使用\\ip访问就可以直接安装打印机，不安装SAMBA的话在设置-打印机-搜索处即可安装

sudo apt-get install samba

修改SAMBA配置文件

sudo nano /etc/samba/smb.conf

把下面的代码加在最后面，如果SAMBA配置文件中有，对比着改就行

# CUPS printing.  
[printers]
comment = All Printers
browseable = no
path = /var/spool/samba
printable = yes
guest ok = yes
read only = yes
create mask = 0700

# Windows clients look for this share name as a source of downloadable
# printer drivers
[print$]
comment = Printer Drivers
path = /var/lib/samba/printers
browseable = yes
read only = no
guest ok = no

重启SAMBA

sudo systemctl restart smbd

现在说说里面的几个注意点：1、在网页端ip:631，如果树莓派能直接识别为网络打印机，最好选用网络打印机，驱动选择IPP everything^TM的,如果没有再选择Local Printers，2、选择Local Printers的话，如果出现有驱动，但无法打印，说明驱动不行，可以来回换，注意要更换名字，因为不更换的话，还是原来的驱动和PPD文件，如果再不行就需要安装新驱动或者换个PPD文件，这个时候请看后面的建议，3、如果以上都不行，请前往相应的打印机厂商的官网下载驱动，选择linux arm的，下载后执行下面的命令安装官方的驱动（记得改路径），一次不成功就安装多次，并且命名最好不好重复，其他细节请看视频。

bash /mnt/data/raspberry/cnijfilter2-6.30-1-deb/install.sh

如果看了视频以及这上面都没有问题，那么配置一下cups文件，这可能有问题

sudo nano /etc/cups/cupsd.conf

配置内容如下

LogLevel warn
