我正在尝试将我的打印机 Laserjet M1212nf MFP 的扫描仪与 xsane 和简单扫描一起使用。首先,我收到以下错误:
Failed open device
'hpaio:usb/HP_LaserJet_Professional_M1212nf_MFP?serial=000000000ST10HPQPR1a':
Error during device I/O.
如果我尝试简单扫描,从图形界面和终端返回的错误是:
unable to connect to scanner.
已安装 hplip 插件,并且 hp-scan -g 提供以下信息:

我按照 Hplip 官方主页的说明重新安装了 hplip 几次,但没有任何效果。任何建议表示赞赏。
