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(推荐)(en)”:
有没有办法检查它们是否有任何不同,或者这只是同一个驱动程序以某种方式打印了多次?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
device for HP_LaserJet_Pro_M501dn: socket://###.###.###.###:9100
device for Unknown: socket://###.###.###.###:9100
HP_LaserJet_Pro_M501dn accepting requests since ср, 07-лис-2018 21:10:12 +0200
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
答案1
只有两个实际文件/usr/share/ppd/HP
hp-laserjet_pro_m501dn-ps.ppd.gz
hp-laserjet_pro_m501n-ps.ppd.gz
所以这是一个驱动程序选择对话框的错误。
