How to Use this Manual vii
Conventions Used in this Manual
The following conventions are used in the command chapters of this manual:
• The emulation(s) to which each command appli es i s gi ven i n parent heses at t he end of the
heading for the command. The emulations (IBM = IBM Propri nter, E = Epson FX, and ML =
OKIDATA MICROLINE Standard) are descri bed i n C hapt er 1.
For example:
Proportional Spacing Commands (IBM/E/ML)
• The printer models to which each command appli es are gi ven i mmedi at el y bel ow t he
command heading, preceded by a check mark (
ML320 E/I, ML321 E/I = Models ML320 & ML321, Epson/IBM-Compatible
ML320 Std., ML321 Std. = Models ML320 & ML 321, MI C ROLI N E Standard Emulation
ML320T, ML321T = Models ML320 Turbo & ML321 Turbo
ML390T, ML391T = Models ML320 Turbo & ML321 Turbo
ML520, ML521 = Models ML520 & ML521
ML590, ML591 = Models ML590 and ML591
For example:
Proportional Spacing Commands (IBM/E/ML)
⻬ ML320 E/I, ML321 E/I ⻬ ML320T, ML321T ⻬ ML520, ML521
⻬ ML320 Std., ML321 Std. ⻬ ML390T, ML391T ⻬ ML590, ML591
⻬).
• Text denoting lines of BASIC programming is set in the Courier font.
For example:
LPRINT CHR$(27);"[@";CHR$(4);CHR$(0);CHR$(0);CHR$(0);
CHR$(34);CHR$(0)
• Notes, which contain important informati on t hat you shoul d read, are set in italics.
For example:
Note: If you send a location value outside the set left or right margin, this command
will be ignored.

Command Summary
This summary is in four sections:
• IBM Commands
• Epson FX Commands
• Epson LQ Commands
• Okidata MICROLINE Standard Commands
Each is section arranged numerically by the deci mal val ue f or t he AS CI I command. The page
number given in the last column refers you to the explanation of the command in this manual.
The printer models which include that particular command are listed in the third column:
䊳 Models ML320 and ML321 incorporate either the Epson FX and IBM Proprinter
emulations (designated as “E/I” in the table) or the OKIDATA MICROLINE Standard
emulation (designated as “Std.” in the table).
Note: If you’re not sure which version of the ML320 or ML321 printer you have, run the
Self Test (hold LF button while turning on the printer), then look at the first line
that prints: if you see EI, you have the Epson/IBM version; i f you see OKI , you
have the OKIDATA MICROLI N E St andard version.
䊳 Models ML 320 Turbo, ML321 Turbo, ML520 and ML521 i ncorporate the IBM Proprinter,
Epson FX and OKIDATA MICROLIN E St andard emulations.
Models ML 390 Turbo, ML391 Turbo, ML590 and ML 591 incorporate the IBM Proprinter, IBM
Proprinter AGM, and Epson LQ emulations.
