我自己的筆記本(基于Ubuntu 16.04的budgie-remix的發(fā)行版)和朋友的NUC主機(Linux Mint 17.3)，各連接了一臺 HP LaserJet 1020 Plus ，安裝了 HPLIP 和 plugin 3.16.5。因為朋友的機器只能通過遠程控制，所以打算在本機調(diào)試找出原因后再處理遠程機器。

兩個環(huán)境第一次連接識別成功，并成功打印測試頁，點擊添加后隨即出現(xiàn) communication error (5012)。刪除后就再也識別不到打印機。終端運行 hp-setup 提示error: No devices found on bus: usb。

NUC：運行l(wèi)susb，有打印機連接，但運行在這個帖子 https://bugs.launchpad.net/hplip/+bug/535056 下看到把當前用戶添加到lp組，重啟終端lsusb，發(fā)現(xiàn)打印機的連接沒了

筆記本：運行 lsusb，未顯示有打印機連接；重新插拔USB線后馬上運行l(wèi)susb，明顯卡頓但輸出仍無打印機連接。拔出打印線，重啟打印機，再插入打印線，觸發(fā)打印機自檢，lsusb可見打印機，回顯如下：

This software comes with ABSOLUTELY NO WARRANTY.

This is free software, and you are welcome to distribute it

under certain conditions. See COPYING file for more details.

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.

但我并未開啟防火墻，cat /etc/services

mdns 5353/tcp # Multicast DNS

mdns 5353/udp

我記得之前裝Ubuntu 15.04 還是15.10的時候，一連接上打印機就自己識別成功，但沒試過重啟后行不行，這個求助帖發(fā)出去之后，就打算重裝回去看看，太難受了，汗。主要是朋友那臺迷你主機，現(xiàn)在能夠安裝成功穩(wěn)定運行的也就是Linux Mint 17.3。
