the print quality is low

When printing with DraftSight (V1R1.4 in winXP), with line widths corresponding to the colors, the print quality is low. Especially patterns appear incomplete.The curved lines are of low quality. I corrected this problem by changing to "additional options" value "print quality" to the max. Printing slows down a bit. I also set the value of _DisplayQuality to 20000. This value can be set as the default or only applies to the current design?The patterns are still incomplete.
