I would like to know how to print with lp commands without using CUPS.

If I send a file to print with this command:

cat fichero.txt | lpr

I've got this error:

lpr cannot open connection to localhost

How can I print or config my system to print using lp commands?

In Ubuntu, there are several packages providing /usr/bin/lpr, one of which is cups-bsd. If you install an alternative you should be able to print without cups. On Redhat-based distros the command you can use to find packages providing a binary is yum whatprovides.

➜  ~ apt-file search /usr/bin/lpr
cups-bsd: /usr/bin/lpr
cups-bsd: /usr/bin/lprm
dvi2ps: /usr/bin/lprdvi
lpr: /usr/bin/lpr
lpr: /usr/bin/lprm
lprng: /usr/bin/lpr
lprng: /usr/bin/lprm
  • I have installed cups-bsd and If I try to print with cat file.txt | lpr I've got this error: lpr: Error - the task scheduler program does not respond. – José Carlos Aug 29 '18 at 11:17
  • But you said you didn't want CUPS - maybe try "lpr" or "lprng"? – GDR Sep 4 '18 at 6:58
  • lpr and lprng doesn't work to me :( – José Carlos Sep 4 '18 at 8:18
