Document the three conditions for printcap(5) to be read.
- On daemon startup
- When a new print job is received
- When receiving a queue control command (lpc disable, enable, stop, etc.)
From the original PR:
It appears to be the case that the print spooler, lpd, re-reads
the /etc/printcap file when changes to that file are made.
This important operational fact is not documented in the lpd(8) man page.
Please revise lpd(8) so as to specify ALL of the times and/or
conditions which will cause lpr to process or reprocess the
current contents of the current /etc/printcap file.
