12. Status Byte Definitions

The status byte always has a base value of 40 hex. Bit 7 (80 hex) is always zero. The

following values may be added to the base value, as appropriate:

Mnemonic Hex value Reset Status condition

STAT_PAPER_OUT 01 No Out of labels

STAT_PAPER_JAM 02 Yes Label is jammed (feed error)

STAT_HARD_ERR 04 Yes General hardware error

STAT_COMM_ERR 08 No Invalid command or I/O error

STAT_IDLE 10 No Printer is idle

STAT_PLATEN_OPEN 20 No Platen is open

If the Reset column indicates "Yes," the printer must be reset to clear the error. The

STAT_COMM_ERR bit is always cleared automatically after the status byte is sent.

Examples:

If a label is jammed in the printer, the status value is 42H:

40 base value

+ 02

label is jammed in printer

If printer is idle and out of labels, the status value is 51H:

40 base value

01 out of labels

+ 10

printer is idle
