我自己的笔记本(基于Ubuntu 16.04的budgie-remix的发行版)和朋友的NUC主机(Linux Mint 17.3)，各连接了一台 HP LaserJet 1020 Plus ，安装了 HPLIP 和 plugin 3.16.5。因为朋友的机器只能通过远程控制，所以打算在本机调试找出原因后再处理远程机器。
两个环境第一次连接识别成功，并成功打印测试页，点击添加后随即出现 communication error (5012)。删除后就再也识别不到打印机。终端运行 hp-setup 提示error: No devices found on bus: usb。
NUC：运行lsusb，有打印机连接，但运行在这个帖子 /hplip/+bug/535056 下看到把当前用户添加到lp组，重启终端lsusb，发现打印机的连接没了
笔记本：运行 lsusb，未显示有打印机连接；重新插拔USB线后马上运行lsusb，明显卡顿但输出仍无打印机连接。拔出打印线，重启打印机，再插入打印线，触发打印机自检，lsusb可见打印机，回显如下：

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or
.run) to determine if the proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an
already built HPLIP supplied tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both
compile- and run-time dependencies).
Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

HPLIP cannot detect devices in your network. This may be due to existing firewall settings blocking the required ports like (5353/udp). When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link.
/node/375
但我并未开启防火墙，cat /etc/services
mdns 5353/tcp # Multicast DNS
mdns 5353/udp
我记得之前装Ubuntu 15.04 还是15.10的时候，一连接上打印机就自己识别成功，但没试过重启后行不行，这个求助帖发出去之后，就打算重装回去看看，太难受了，汗。主要是朋友那台迷你主机，现在能够安装成功稳定运行的也就是Linux Mint 17.3。
