Status Readback
Introduction
This chapter describes the PCL status readback features.
PCL status is requested from the printer with the commands
described in this chapter. Following a status request, the printer
generates a status response. This response consists of ASCII
data which is sent directly from the printer, through the I/O, back
to the host. Status readback allows you to obtain information
from the printer such as: available printer (user) memory,
current available fonts and symbol sets, and the ID numbers
of downloaded macros and user-defined patterns to verify
their presence.
