After configuring printing on a Linux server, the administrator sends a test file to one of the printers and it fails to print. What command can be used to display the status of the printer's queue? (Specify ONLY the command without any path or parameters.)
Answer: lpq 或 lpstat
題解
「lpq」(/usr/bin/lpq)指令可以顯示列印佇列的狀態。「lpstat」(/usr/bin/lpstat)指令可以顯CUPS系統的狀態，包含列印佇列的狀態。
