LA - Line attribute
LA [ l, v [ , l , v [ , l , v]]] [;]
l ; line attribute v : value
 This command specifies the shape of line joins and line ends.
 These settings are effective for the line widths thicker than 0.35 mm.
 l specifies the line attribute for which you are setting a value.
 There are three line attributes - line end type, line join type and miter limit, specified by line attribute
values of 1, 2 and 3 respectively.
 v specifies the value of the particular attribute.
 Line ends are either butt (1), square (2,), triangular (3) or round (4).
 Line joins are either mitered (1), mitered/beveled (2), triangular (3), round (4), beveled (5), or have no join
(6).
 Miter limit is the ratio of miter length to line width. When the miter limit is exceeded, the join is clipped
to the miter limit.
 The miter limit is specified as a clamped real number.
 If no parameters are specified, the line attributes are set as follows: line ends are butt, line joins are
mitered and the miter limit is 5. This is equivalent to the command LA1, 1, 2, 1, 3, 5;
Miter length
Line width
Miter limit = Miter length / Line width
 Labels are always drawn with rounded ends and joins.
 An LA command remains in effect until another LA command is issued, until default settings are restored
with the DF command or until the printer is initialized with an IN command.
