尝试在 KDE 中设置 HP LaserJet Pro M501 (m501dn) 时,我在驱动程序选择对话框中获得了多个 (8) 相同驱动程序的列表,名为“LaserJet Pro M501 Postscript (recommended) (en)”:
有没有办法检查它们是否有任何不同,或者这是否只是以某种方式多次打印的同一个驱动程序?升级到 18.04 后我无法使用双面打印
$ lpstat -t M501
scheduler is running
no system default destination

Unknown accepting requests since ср, 07-лис-2018 21:00:18 +0200
printer HP_LaserJet_Pro_M501dn is idle. enabled since ср, 07-лис-2018 21:10:12 +0200
printer Unknown is idle. enabled since ср, 07-лис-2018 21:00:18 +0200
里面只有两个实际文件
/usr/share/ppd/HP
所以这是驱动程序选择对话框的错误。
