ESC ENQ 6		Status Report
1B 05 06	hex
27 5 6	decimal

Results in a 2-byte response, reflecting the status of each sensor. This command is intended as a go/no go indication. When everything is OK, this status report returns 0.

Note • If no weekend sensor is installed, 64 is returned when everything is OK. If no weekend or paper-near-end sensors are installed, 64+2=66 is returned when OK.

****

This bit indicates that an error code is available. Use <ESC><ENQ><1> to fetch it.

This bit tells you that there are data in the printer that have 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 Enquiry on page 57.

Bits 0, 3, and 5 in the first byte are reset when read.
