When the slip paper is selected and the printer goes to the slip waiting state: Bits 5 and 6 of the third byte is 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 stop due to paper-end is disabled using 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 DIP SW 2-5 is off, n = 2 when DIP SW 2-5 is on [Reference] DLE EOT, ESC u, ESC v, GS ENQ, GS r, APPENDIX B, APPENDIX F TITLE EPSON TM-U950/U950P Specification (STANDARD) SHEET REVISION NO.
