16 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.
