我目前正在使用 ubuntu 20.04，并且有一个HP 打印机 Deskjet 5822。我通常安装制造商本身提供的驱动程序，因为它们会根据官方规范存储库进行更新。
安装软件包后，我开始注意到一个缺陷，系统通知我打印机存在通信问题。原理怀疑可能是电缆的问题，因为我总是通过 USB 连接。但在 Windows 机器上的测试中，打印机工作正常，只有在 ubuntu 上才会出现问题。
在论坛搜索中，我注意到有几个人遇到了杯子模块和高压磷脂酰肌醇。最初安装时我也遇到了类似的问题，因为hplip-gui没有找到打印机的 ppd 文件。此类问题是由于 CUPS 进程被关闭而引起的。在激活杯子，当前的问题在于通信，因为它会生成两个打印机输入，因此不允许使用打印机，因为它无法正常通信。
为了帮助分析，生成了一个错误报告，生成方式如下hp-check：
HP Linux Imaging and Printing System (ver. 3.20.5)
Dependency/Version Check Utility ver. 15.1
Copyright (c) 2001-18 HP Development Company, LP
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]
