我使用 Epson WF 7510 打印机，并且可以使用系统工具 (OS X) 以我选择的任何质量（草稿/正常/最佳）进行打印。但我无法更改命令行中的打印质量：lp -o EPIJ_Qual=...没有效果。
如何更改打印质量？

使用其他选项（如）也-o EPIJ_Hori=1有效果。
答案1
-o print-quality=3您尝试过使用4/5 或 4/5选项吗？
例如：
lp -o print-quality=3 filename
参考：lpr 手册页
对于 Ubuntu 18.04 下的 Epson SX405，它不起作用。
我输入lpoptions -l | grep [Qq]uality，它给出：
StpQuality/Print Quality: None Economy Draft *Standard High Photo HighPhoto UltraPhoto Best
StpBandEnhancement/Quality Enhancement: *None 0 1 2 3 4
然后lp -o StpQuality=Economy filename工作...
