STATUS/INFORMATION
Get Printer Status
Format:
ESC (0x1b) ‘h’ (0x68)
This command requests a status byte from the printer. If one is returned, it indicates that the printer is
operational and has finished processing the previous label. It should be called before loading or printing
a label in order to make sure that the host software is synchronized with the printer. If bit 3 of the status
byte is high, it indicates that the battery is low. If bit 4 is high, it indicates that the printer has been
powered on and reset (see the Reset Status function). This command requests a status byte from the
printer with the following format:
Bit Description
4 Printer reset (0=reset cleared, 1=printer reset)
3 Battery status (0=voltage OK, 1=low battery)
2 Latch status (0=latch closed, 1=latch open)
1 Paper status (0=paper present, 1= out of paper)
0 Printer status (0=printer ready, 1=printer busy)
