+# Cups: The Common Unix Printing System
+
+Configure cups at /etc/cups/supsd.conf, or visit the local webpage at http://localhost:631 if you want to use the Apple interface, otherwise, it's the printing daemon.
+
+# The Printing Daemon
+
+The printing daemon automatically reads the cups configuration file.  It prints with:
+
+> lp mytext.txt
+
+Find a list of printers with:
+
+> lpq
+
+You can specify a printer with `-d`:
+
+> lp -d DCP7060D article.pdf
+
+Alternatively, if you see a printer number, cancel job 33 with:
+
+> lprm 33
+
+or just cancel all jobs:
+
+> lprm -
+
+See printers on network:
+
+> lpstat -a
+
+Block or accept all jobs with:
+
+> cupsreject DCP7060D
+
+> cupsaccept DCP7060D
+
