Bit 1 becomes 0 (possible to print) when paper loading has finished and is 1 when slip ejection is started or when time out.
When the slip paper is selected and the printer goes to the slip waiting state:
. Bits 5 and 6 of the third byte are 1 (no paper)
. Bits 0 and 1 of the fourth byte are 0 (selected) and 1 (impossible to print), respectively.
When the printer goes to the slip ejection waiting with slip selected:
. Bits 5 and 6 of the third byte are 1 (no paper) and 0 (paper present), respectively.
. Bits 0 and 1 of the fourth byte are 0 (selected) and 1 (impossible to print), respectively.
When printing stops due to paper-end disabled by ESC c 4, bit 1 of the fourth byte (slip status) does not become 1 (impossible to print)
even when there is no remaining printing space on the slip. Use GS r 3 to check the remaining printing space on the slip.
Default: n = 0, when “ BUSY OFFLINE: YES” is selected via setup,
