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

23-22 The Character Group EN
The thickness of fill lines for hatching and cross hatch is selected
using the PW (Pen Width) command. Due to the way hatching and
cross-hatch lines are drawn, they may extend beyond the character
outline by up to 1/2 of the current pen width. When using a small pen
width and specifying a black edge pen, the edging covers up hatching
lines that extend outside the character outline. However, as the pen
width increases, the edge pen may not be wide enough to
compensate for this, resulting in a fill that overlaps the character
edges. To ensure that the character fill looks correct when using
hatching patterns, use a narrow pen width, especially for small point
sizes (see illustration below).
