Table 4 • Sensor Status
* This bit indicates that a status code is available. Use ESC
ENQ 1 or ESC ENQ E
to fetch it.
** This bit tells you that there is data in the printer that has not yet been printed. There
are two possible reasons for that:
1) The last command received by the printer was not a command that triggers a
printout.
2) The printer is printing
*** When parallel cable is connected, both printer and host computer must have been
off to set this bit. This is because the interface powers the RAM in the printer.
**** This paper-near-end bit differs from the ESC ENQ 2 response, see Paper-near-end
