How to list printer names acceptable for use with lpr?

$ lpstat -p -d

From the CUPS manual.

To get a list you can use:

lpstat -a

or

cat /etc/printcap

To print only the printer names:

lpstat + read + array:

$ while read l; do l=($l); echo "${l[0]}"; done <<< "$(lpstat -a)"

lpstat + awk:

$ lpstat -a | awk '{print $1}'

lpstat + cut:

$ lpstat -a | cut -f1 -d ' '

cat + grep + cut in /etc/printcap:

$ cat /etc/printcap | cut -f1 -d'|' | grep '^#' -v

This is what is shown, one per line:

HP_LaserJet_P1606dn
HP_Deskjet_2540_series
HP_LaserJet_M1212nf
GCP-Save_to_Google_Docs

I feel like the lpstat solutions are more elegant and reliable. Mostly because /etc/printcap was not found on some systems I tested.

About using awk or cut, depends on what you have installed and prefer. The bash read + bash array option should work on any bash shell without the need for externals.

EDIT : I said the marked solution does no work for me on Amazon Linux. But I guess it works if you just want to copy the printer names from the middle of the rest of the output. Works the same as using just lpstat -a.

$ lpstat -p -d
