Flush All Pages Command
ESC&r#F

• #=0 suspends receiving data and ejects all complete data. Incompleted data remains in the printers memory.
• #=1 suspends receiving data and ejects all data remaining in the printer memory.
Echo Command
ESC*s#X
This command is used to distinguish each request and response. In networking/sharing environments, some
requests may be sent from a number of PCs to one printer. This command sends the user selected value to the
printer and the printer can return the same value. Adding this command before the status request command allows
this echo value to distinguish the corresponding status response.
