Chapter 4 Configuring the Epson FX-1050 Emulation with Control Codes

Double Wide Print (One Line)

ASCII Code SO ESC SO

Hex Code 0E 1B 0E

Dec Code 14 27 14

Purpose Selects double wide print for one line only.

Discussion This control code is a line-by-line print attribute; when SO or

ESC SO is received, the characters on the current line print

twice as wide, then automatically reset.

This control code is cancelled by the DC4 code or by a CR code,

as in the Epson FX-1050. It is

also

cancelled by a paper motion

control code (LF, VT, etc.), as in the IBM Proprinter III XL.

†

This control code doubles character width, but does

not

double

inter-character spacing, unlike the Epson FX-1050. The formulas

for total character spacing are as follows:

Epson FX-1050 2(char + 1 dot + space)

Epson Emulation 2(char + 1 dot) + space

Example The following sample illustrates double wide print for one line

only.

Double Wide Print (One Line), Cancel

ASCII Code DC4

Hex Code 14

Dec Code 20

Purpose Cancels the double wide print for one line only selected by SO or

ESC SO.

Discussion This command cancels the double wide print selected by SO or

ESC SO, but does not cancel double wide printing selected by

ESC W or ESC !.
