* The following macro computes the number of seconds to sleep
* AFTER waiting for the system buffers to be drained.
*
* Various choices:
*
* - A percentage (perhaps even >100%) of the time it would
* take to print the printer's buffer. Use this if it appears
* the printers are affected if the port is closed before they
* finish printing.
*
* - 0. Use this to avoid any extra sleep after waiting for the
* system buffers to be flushed.
*
* - N > 0. Use this to have a fixed sleep after flushing the
* system buffers.
*
* The sleep period can be overridden by a single command line argument.
