Horizontal Tab (HT)
3. If the top margin (TM) is currently greater than 1, then TM minus 1 of ASCII
line feed characters (X' OA ') are sent.
4. If the left margin (LM) is currently greater than 1, then LM minus 1 of ASCII
space characters (X' 20') are sent.
The Horizontal Tab (HT) is a format control that moves the print position
horizontally to the next tab stop setting. Horizontal tab stop values are set by using
the Set Horizontal Format (SHF) function. If there are no horizontal tab stops set
to the right of the current print position, the horizontal tab function generates a
space.
To execute this command, the 3708 sends the number of ASCII space characters
(X' 20') required to cause the print element to move to the next tab setting.
Note: An HT placed after the MPP causes a space in the first print position of the
next line.
Inhibit Presentation (INP)
The Inhibit Presentation (lNP) is a format control used to inhibit the printing of
keyboard input data. This command performs no function on an LU type 1 device.
It is accepted by the 3708 without an error response and without affecting the
printout format.
Interrecord Separator (IRS)
Line Feed (LF)
New Line (NL)
The Interrecord Separator (IRS) is a separator character that causes a newline
function.
The Line Feed (LF) is a format control that moves the print position down to the
next line.
To execute this command, the 3708 sends XLATE (X'25').
The New Line (NL) is a format control that moves the print position to the left
margin on the next line. This is functionally equivalent to a CR followed by a LF.
To execute this command, the 3708 sends:
1. XLA TE (X' OD ') to perform the carriage return function.
2. If a carriage return delay is specified for the port to which the printer is
attached, a number of ASCII DEL characters (X '7F') are sent to the printer.
The number of DEL characters is determined by multiplying the configured
carriage-return-delay value by the ratio of the current column to the platen
width.
Note: Instead of DEL (X'7F') characters, the user may configure the 3708 to
transmit NULL (X' 00') or XON (X' 11') by setting nonstandard bits 4 or 10
to 1.
3. If a carriage-return-delay character is specified for the port to which the printer
is attached, a number of ASCII DEL characters (X' 7F ') are sent to the printer.
The number of DEL characters is equal to the carriage-return-delay value.
