Centos 6 识别并配置了通过 USB 连接的 HP LaserJet P3015dn 打印机。此机器配置为小组文件/打印服务器。我可以打印测试页，该页处理/打印正确。下次尝试打印时（例如打印第二张测试页），不会打印该页面，并且打印机设置为禁用。打印机的状态如下：
Stopped - /usr/lib/cups/backend/hp failed
在打印机配置对话框中。
/var/log/cups/error_log包含此信息（前两行是在打印作业失败之前出现的）

我现在不知道如何让这台打印机在我的 Centos 机器上运行。如何配置机器以打印多个打印作业而无需反复拔插？
答案1
HP LaserJet P3015dn 是一款完全支持 Linux 和 CUPS 的打印机。“dn”表示“双面和联网”。因此，排除工作站和（哎呀）USB 连接的一种快速干净的方法是通过以太网连接此打印机。无论如何，这可能是长期采取的更好方法。
答案2
您是否考虑过联系 HP 以获取可能的打印机驱动程序和/或固件更新？
