EXPANDED MEMORY OPTION COMMANDS
These commands require the optional Expanded Memory.
Note: Before Expanded Memory can be used for the first time, it must be initialized
using the <ESC>BJF command. If it is not initialized, the printer will not recognize the
memory and respond as if no expanded memory was installed.
