HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

22-22 The Line and Fill Attributes Group EN
LT, Line Type
This command specifies the line pattern to be used when drawing
lines. Use LT to vary lines and enhance your plot. Note that the ends
of dashed line segments in a line pattern are affected by current line
attributes (refer to the LA command earlier in this chapter).
LT line type[,pattern length[,mode;]]
or
LT [;]
or
LT99 [;]
The LT command applies to lines drawn by the AA, AR, AT, CI, EA,
EP, ER, EW, FP, PA, PD, PE, PR, RA, RR, RT, and WG commands.
Line types are drawn using the current line attributes set by the Line
Attribute (LA) command. For example, if you have used LA to specify
rounded ends, the printer draws each dash in a dashed line pattern
with rounded ends.
z No Parameters- Defaults the line type to solid and saves the
previous line type, pattern length, and any unused portion of
the pattern (residue).
z Line Type- Subsequent lines are drawn with the corresponding
line pattern. Line patterns can be of fixed or adaptive type.
