C
It is used to configure:
- The number of printer columns: between 10 and 132 (132 by
default).
This is the number of characters that can be printed on one line (this
depends on the type and/or mode of the connected printer). The most
common values are 80 and 132.
- Automatic line skip option: (checked by default)
To go to the beginning of the next line on a printer, two characters
must be sent: CR for Carriage Return (the print head is repositioned
at the beginning of the line without a vertical shift) and LF for Line
Feed (the paper is shifted up one line). In order to use less of the
passband, certain printers automatically generate the LF character
when they receive the CR character. When the box is checked, only
the CR character is sent to the printer. However, if this parameter is
configured incorrectly, the following scenarios may arise:
- The box is checked and the printer does not support auto-LF: All
the printed text will be superimposed on one another.
- The box is unchecked and the printer supports auto-LF: All lines
will be separated by a blank line.
- The transfer speed: (9600 by default)
This is the communication speed configured for the printer. It depends
on the type of printer connected. If random printing errors occur, this
speed must be reduced on the XBT L100• and on the printer.
- Option for the printer to use the XON/XOFF protocol: (not
checked by default)
When the terminal sends data to be printed to the printer, the latter
usually stores them in a buffer of limited size. In order to regulate the
communication flow, some printers use a protocol called XON/XOFF:
When the printer buffer reaches 80% saturation, the printer sends an
XOFF command to the terminal, which then suspends printing until
the printer sends it an XON character.
When the box is checked, this function is activated. If the box is not
checked, there is no flow control. This protocol needs a 3-wire cable
(earth, send channel, receive channel) to operate.
