./run.sh failed outright with ModuleNotFoundError, and once running it reported a sleeping printer as a critical paper jam. Both are fixed, plus the defects found while verifying them against the real HL-1110. Entry point: run.sh ran the script by path, so the absolute python_pkg.* imports could not resolve. Resolve the repo root and pass PYTHONPATH as a sudo argument, since sudo's env_reset strips an exported one. __main__.py had the wrong import prefix and ran main() on import. Status codes: the table claimed provenance from a "Brother PJL Technical Reference" that does not appear to exist, and 23 of its 25 entries were wrong. Rebuilt from the HP PJL Technical Reference Manual, Appendix D, and verified against six states induced on real hardware (10001 READY, 10003 WARMING UP, 10023 PRINTING, 40000 SLEEP, 40021 TOP COVER OPEN, 41213 NO PAPER) - all six matched the reference, none matched the table. 40000 is SLEEP MODE, which the reference explicitly flags "not an error"; the real jam code 40022 was absent entirely. The inverse also bit: 10006 is TONER LOW, previously shown as a benign "Processing". Codes in no reference are dropped and now report "Unknown status - check printer display" rather than a confident wrong answer, and states we infer ourselves no longer borrow PJL numbers to describe themselves. Page counts: estimates came from the CUPS page log, which only sees jobs CUPS logged and counts pages the printer never printed (it logged total=50 for a job that printed 3). Take them from @PJL INFO PAGECOUNT instead, migrating stored baselines onto the printer's scale once so the reported percentages do not jump. Reading status must not cost anything: a blocking open() hung forever whenever the printer was unwell - precisely when a status report is wanted - and the port-status probe stopped CUPS and reset the USB device, destroying the in-flight job and then misreporting the damage as a printer error. The fd is now non-blocking with deadline-bounded writes, and the probe reads the same byte via the free usblp ioctl, skips entirely while a job prints, and re-attaches the kernel driver. Dropped pages: the HL-1110 silently discards pages whose 600dpi raster exceeds its ~1MB memory, stays READY, and CUPS still calls the job successful - so nothing anywhere reports the failure. Compare CUPS's claim against the printer's counter between jobs and name the workaround (lp -o Resolution=300dpi). 402 tests, 100% branch coverage.
