The SOH shutdown command isrequired before loading images or fonts because some may contain data sequences that could beinterpreted as Immediate Commands. After the SOH shutdown command is sent, ImmediateCommands can be turned back on by sending a valid SOH command three times, separated by a onesecond delay between each command, or by manually resetting the printer. It is good practice tocheck batch quantities (E) to verify that the SOH commands are working.Syntax: DSample: DPrinter Response: This printer will ignore Immediate Commands (^A) until a valid SOHcommand is received three times, separated by a one second delay betweeneach command; or, until the printer is manually reset.
