Using SQ-2000 Commands with BASIC Master Select Codes

Most versions of BASIC use the LPRINT command and the CHR$(n) function to send codes to the printer. In the CHR$(n) function the value n is the number of the code that you want to send to the printer. For example, to set a right margin at column 60, the SQ-2000 command is:

<ESC> “Q” 60

In BASIC it looks like this: LPRINT CHR$(27) “Q” CHR$(60);

<ESC>	“T”	Cancels superscripts and subscripts.
Character Set Commands
<ESC> “%” n		Selects the user-defined character set (n=1) or cancels
		the user-defined character set (n=0).
<ESC> “&” <NUL> n1 n2 data
		Defines user-defined characters
<ESC> “.” <NUL> <NUL> <NUL>
		Copies ROM character set to user-defined character set.

<ESC> “L” n1	n2 data	Prints double-density dot graphics.
<ESC> “Y” n1	n2 data	Prints high-speed double-density dot graphics.
<ESC> “Z“ n1 n2 data		Prints quadruple-density dot graphics.
<ESC> “*” s n1 n2 data		prints selected-density dot graphics.
<ESC> “?” s n		Assigns graphics densities.

Miscellaneous Commands

<CAN>	Cancels the current line.
<DEL>	Deletes the preceding character.
<DC3>	Turns printer to off-line state.
<DC1>	Turns printer to on-line state.

<ESC> “V” n data <ESC> “V” <NUL>

Repeats data, n times Sets the eighth data bit to 1.

Sets the eighth data bit to 0.

Cancels control of the eighth data bit. Sounds the buzzer.

Produces a backspace. Resets the printer.

Causes the next line to be printed left-to-right. Selects unidirectional printing (n=1) or bidirectional printing (n=0).

Each print style is assigned a value to be used with the Master Select com- mand. The Master Select command consists of <ESC> ’!” followed by a single ASCII code. To create a Master Select code, add the values of the print styles you want to combine.

The values of the print styles are as follows:

Elite	1
Proportional	2
Compressed	4
Emphasized	8
Expanded	32
Italic	64
Underlined	128

For example, if you want to find the code for elite emphasized italic print you would add these values:

Elite Emphasized Italic

Master Select code

The Master Select Command you would use would look like this:

<ESC> “!” “I”(I is ASCII 73)
