Small improvements
1. The printer will now retry three times (cut + clear presenter), when
failing to clear the presenter.
2. Short delay (1 s) added before autoload starts, to avoid paper jam and
limit noise at start of autoload.
3. Parameter n36 (Document mode) extended with “2-Black mark
mode”.
4. Parameter n49 defaults to 1
5. Parameter n56 “Max status code” added (default value: 255).
6. Print buffer handling Speeded-up
7. nFault (parallel port) will now be set on at types of general faults.
8. ESC ‘P’ + unknown, will terminate ESC ‘P’ command sequence.
9. Adding an ACK-marker will now force printout.
Bug fixes
1. Parallel and USB IRQ are only enabled when detected
2. Speed-compensation when using long burn times and high speed
improved.
3. The error state clean up process will make sure that a found ACK-
marker will be answered before deleted.
4. The printer will no longer report PrintDataInBuffer when it’s in
TestMode, otherwise the driver will try to clear it up, and causing two-
three extra empty receipts.
5. Fixed where the Feed Button stops responding [1756-256:A1].
6. Fixed the bug where ESC ENQ 06h reported an pending error, but ESC
ENQ 01 said “No error”
7. The FF-button will now work regardless of how “AutoCut after FF”
(parameter 34) is set.
8. The test receipt didn’t print parameter 49 correctly, now fixed.
