SYSVAR, cont.
Remarks, cont. 25. Type of Centronics communication (Set or Read)
Three types of Centronics communication in the compatible mode
can be selected or read. (Nibble, byte, ECP and EPP are presently
not supported.)
SYSVAR(25) = 0 Standard type
Predefi ned timing for the ACK and BUSY signals
when responding to host data is:
500 ns ACK, BUSY inactivated after ACK
fi nishes.
SYSVAR(25) = 1 IBM/Epson type
Predefi ned timing for the ACK and BUSY signals
when responding to host data is:
2500 ns ACK, BUSY inactivated as soon as ACK
pulse starts.
SYSVAR(25) = 2 Classic type
Predefi ned timing for the ACK and BUSY signals
when responding to host data is:
BUSY deactivated, wait 2500 ns, then give 2500
ns pulse on ACK.
Default: 0 = Standard type
26: Ribbon low condition (Read only)
This parameter allows you to read the status of the ribbon low sensor in
EasyCoder F-series thermal transfer printers. In the Setup Mode, you can
specify a diameter in mm of the ribbon supply roll, when the SYSVAR(26)
will switch from 0 to 1.
The printer returns:
0 = Ribbon not low
1 = Ribbon low
28. Erase paper feed data at headlift (Set only)
The fi rmware keeps track of all labels (or similar) between the label stop
sensor and the dot line of the printhead. If the printhead is lifted, there is a large
risk that the paper is moved, so the paper feed will not work correctly before
those labels have been fed out. This parameter allows you to decide whether
these data should be cleared when the printhead is lifted or not.
SYSVAR(28) = 0 Media feed data are not cleared at headlift
SYSVAR(28) = 1 Media feed data are cleared at headlift (default)
29: DSR condition on "uart2:" (Read only)
This parameter allows you to read the DSR (Data Send Ready) condition
on the serial channel "uart2:"
The printer returns:
0 = No
1 = Yes
