Linux下一般使用sane做为扫描仪后端，安装如下：
sudo apt-get install sane sane-utils xsane
kirchhoff@kirchhoff-dell:~/Downloads$ sudo sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x4c17 [HP LaserJet M1522nf MFP]) at libusb:003:010
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend’s manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can’t be detected by this program.
kirchhoff@kirchhoff-dell:~/Downloads$ scanimage -L
device `hpaio:/usb/HP_LaserJet_M1522nf_MFP?serial=00XXXXXXXXXX’ is a Hewlett-Packard HP_LaserJet_M1522nf_MFP all-in-one
此时能够打印，但是打开xsane的图形界面仍然 报ioerror

我这里是已经安装好了的界面，在未解决此问题之前，这个插件是没有安装好的，最好指定插件的路径进行安装，因为在线下载了好几遍依然下载不下来，具体的插件网络路径是https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/
可以预先下载好plugin.run和asc，即可安装成功。
