在某台打印机上打印时，杯子总是要求输入密码
当我将打印发送到网络打印机（HP Laserjet 2200d）时，CUPS要求输入用户名/密码。 其他打印机不会发生这种情况，我确定它是一个CUPS问题，因为即使我没有连接到网络，它也会询问密码。
这是我的/etc/cups/cupsd.conf ：
# # # Sample configuration file for the CUPS scheduler. See "man cupsd.conf" for a # complete description of this file. # # Log general information in error_log - change "warn" to "debug" # for troubleshooting...

由于您说它只是一台显示此行为的打印机，因此错误可能出现在/etc/cups/printers.conf 。
检查要求输入密码的打印机的授权条目。
