lp -d printer_name file.txt
This will print the file file.txt to the printer with the name printer_name.
Explanation in detail:
If you have multiple printers installed on your system and you want to specify which one to use, you can use the -d option to select the desired printer.
You can also use the lpstat -p command to list all available printers on the system, which can be useful if you are unsure of the exact name of the printer you want to use.
For example:
lpstat -p
This will display a list of all available printers on the system, along with their names and status. You can then use the -d option to specify the desired printer when printing a file.
Note that the lp command and the lpstat command are part of the CUPS (Common Unix Printing System) and are available on most Unix-like operating systems, including Linux and macOS. The exact syntax and options may vary depending on your system and the version of CUPS you are using.
