Table D-3. AMT Datasouth and Diablo 630 Escape Sequences––continued
Function ASCII Hexadecimal Decimal Description
Margins, Tabs and Page Formatting––continued
Set right margin ........................ ESC 0 1B 30 27 48 This sequence sets the right margin at the current print position
for use by the automatic center and justify modes. The right
margin setting is a soft margin that does not affect normal
printing or cause automatic line wrapping. The right margin is a
function of character spacing. Therefore, when character
spacing changes, the right margin remains at the same print
position, but not at the same place on the page.
Set top margin........................... ESC T 1B 54 27 84 This sequence sets the top margin at the current line posi-tion.
The printer advances each new page to this position before
printing begins. It is possible to access the area above the top
margin using absolute or relative moves, or reverse line feeds.
The top margin clears when the printer receives a Clear Top and
Bottom Margins sequence, Set Lines Per Page sequence, or the
operator sets a new page length from the control panel. The
physical location of the top margin on the page is unaffected by
subsequent changes to line spacing.
Set bottom margin .................... ESC L 1B 4C 27 76 This sequence sets the bottom margin at the current line position.
After printing on this line, the printer feeds a new sheet; no
printing can occur below the bottom margin. The bottom margin
clears when the printer receives a Clear Top and Bottom Margins
sequence, Set Lines Per Page sequence, or the operator sets a
new page length from the control panel. The physical location of
the bottom margin on the page is unaffected by subsequent
changes to line spacing.
Clear top/bottom margins........ ESC C 1B 43 27 67 This sequence clears the top and bottom margin settings so that
printing can occur on any line on the page.
Clear all tab stops ..................... ESC 2 1B 32 27 50 This sequence clears all previously set horizontal and vertical tab
stops.
Set single horizontal tab ........... ESC 1 1B 31 27 49 This sequence sets a horizontal tab stop at the current print
stop position. Tab stops can be set at any of the first 159 print
positions on a line. Horizontal tab stops are a function of the
current character spacing. Therefore, when character spacing
changes, horizontal tabs remain at the same print positions, but
not at the same places on the page. If the factory defaults are in
effect, horizontal tab stops are set every eight print positions
across the page.
Clear single horizontal ............. ESC 8 1B 38 27 56 This sequence clears the horizontal tab stop at the current
tab stop print position.
