Chapter 2 Program Instructions
Remarks, cont'd. 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
Predefined timing for the ACK and BUSY signals
when responding to host data is:
500 ns ACK, BUSY inactivated after ACK finishes.
SYSVAR(25) = 1 IBM/Epson type
Predefined 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
Predefined 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
28. Erase paper feed data at headlift (Set only)
The firmware 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 Paper feed data are not cleared at headlift (default)
SYSVAR(28) = 1 Paper feed data are cleared at headlift
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
30: DSR condition on "uart3:" (Read only)
This parameter allows you to read the DSR (Data Send Ready) condition on
the serial channel "uart3:"
The printer returns:
0 = No
1 = Yes
