COUNTER STATUS (SOH + ME)
Receipt of SOH followed by ME causes the printer to return information bounded by an STX-ETX
pair that reports the operating status of the printer's life counters.
SENSOR STATUS (SOH + SG)
Receipt of SOH followed by SG causes the printer to return information bounded by an STX-ETX
pair that reports the current operating status of the printer's sensors. Refer to Appendix: Table
HEAD STATUS (SOH + HC)
Receipt of SOH followed by HC causes the printer to return information bounded by an STX-ETX
pair that reports the current operating status of the print head.
SYSTEM VERSION INFORMATION (SOH + SB)
Receipt of SOH followed by SB causes the printer to return information bounded by an STX-ETX
pair that reports the system version of the printer.
MEMORY STATUS (SOH + EB)
Receipt of SOH followed by EB causes the printer to return information bounded by an STX-ETX
pair that reports the current user memory allocation.
FORM OVERLAY STATUS (SOH + FO)
Receipt of SOH followed by FO causes the printer to return information bounded by an STX-ETX
pair that reports the forms downloaded into the printer.
FONT CONFIGURATION (SOH + FG)
Receipt of SOH followed by FG causes the printer to return information bounded by an STX-ETX
pair that reports information on the stored font or graphic.
INTERFACE STATUS (SOH + IG)
Receipt of SOH followed by IG causes the printer to return information bounded by an STX-ETX
pair that reports the type of interface connection currently set.
