SP, Select Pen

This command selects the printer’s ‘logical’ pen for subsequent plotting. An SP command must be included at the beginning of each command sequence to enable the printer to draw.

SP pen number[;]

or

SP [;]

Parameter	Format	Functional Range	Default
pen number	integer	0 or 1	No pen

Although your printer does not have physical pens, for the purpose of compatibility it has a ‘logical’ pen which you must select to print your drawing.

zNo Parameters— Cancels pen selection; subsequent plotting commands are not drawn. Equivalent to (SP0).

zPen Number— Selects the printer’s ‘logical’ pen. The printer will not draw unless an SP is sent.

z0 — Selects the white pen. To see a white pen on a non-white background you must set transparency mode to OFF (TR0;).

z1 — Selects the black pen; numbers greater than 1 are also interpreted as 1.

Use the Pen Width (PW) command to change the line width. You may change widths as often as you like, without sending an SP command again.

Note	If you are not using the Transparency Mode (TR) command, white is
	always transparent. For more information on the Transparency Mode
	command, see the TR command description later in this chapter.
