See also command “Expanded flash memory allocation” (1D 22 80...) and “Select flash area” (1D 22 81 n).
Important: While erasing flash memory, the printer disables all interrupts, including communications. To provide feedback
to the application, the printer responds to the application when the erase is complete with a 0D (Hex). After sending the
erase user flash sector (1D 40 n) command, an application should wait for the response from the printer before sending
data. Otherwise, data will be lost. If an application is unable to receive data, it should wait a minimum of ten seconds after
sending the erase user flash sector (1D 40 n) command before sending data.
