lpinfo 命令

常用示例

说明

lpinfo lists available printers and printer drivers known to CUPS. It queries the CUPS server for devices and PPD (PostScript Printer Description) files. Device listing (-v) shows all detected printer connections including USB, network, and parallel ports. Each entry includes a device URI that can be used when adding printers with lpadmin. Driver listing (-m) shows PPD files that describe printer capabilities. PPDs define paper sizes, resolutions, color options, and other features. Driverless printing uses generic IPP Everywhere or AirPrint drivers. The make-and-model filter helps find drivers for specific printers. Combined with grep, you can search for compatible drivers for your hardware. Network printer discovery may include DNS-SD (Bonjour/Avahi) discovered printers. Use scheme filters to focus on specific connection types.
