Detailed Description

The Printer class is a function object that takes a const char* parameter as input and returns void. The following options determine the behaviour:

linewise If true (default), waits until EOL or EOF has been written to the stream before sending the output to Printer. If false, calls Printer for every character written to the stream.
passthrough If true (default), sends all characters to the original stream as well. If false, sends characters to Printer only.
