Command: Set Single Line Distance (SSLD)
Format: 2B D2 nn 15 ldld
Printers: 3812, 4214, 5219
Action: Specifies in 1/1440-inch units the distance between
subsequent print lines. This command overrides the last
Set Single Line Distance or Set Line Density (SLD)
command. Set Single Line Distance has the same effect
as Set Line Density, with the exception that the units are
different.
The ldld parameter specifies the height of a print line in
1/1440-inch units.
For the 5219, the following ldld parameter values are
supported: 001Eh (48 LPI), 003Ch (24 LPI), 0078h (12
LPI), 0096h (9.6 LPI), 00B4h (8 PLI), 00F0h (6 LPI),
010Eh (5.33 LPI), 168h (4 LPI) and 023Ah (1 line per
centimeter).
For the 4214, all values are valid and are translated to
equivalent 1/72-inch units.
For the 3812, values between 0001h and 7FFFh are
valid.
IBMEMUL: Same as the 3812. All values of the ldld parameter are
supported.
The 5250 ALLY maintains all vertical movement
distances in 1/1440-inch units; however, actual
commands to the target printer are translated to the
equivalent units specified by Option 48 — Vertical
Resolution. This means that the accumulated error across
multiple lines of text is never more than one-half of the
target printer’s vertical resolution.
275EMUL: No operation.
