[Description] When the printer controller receives this command, it will send a status byte.
Notes:
When an error occurs, the printer status LED flashes 1:1
If during a printout a paper end occurs (82h), the printer doesn't send anymore its status byte
(even with ESC k command) untill a new paper roll has been loaded or printer has been reset
(this is a normal behaviour of the printer).
To prevent that balances of old print orders are printed immediately after closing the printer
Cover and causing a paper jam, an error lag of about 2 seconds has been installed. In case of
an error, the printer mechanism is blocked for 2 seconds after its remedy. This gives the user
enough time to close the lid without having the printer run immediately.
The bits are defined as follows:
