Problem

When plotting in XM some elements not plotting correctly as in weight, style, etc. Works fine using printer.plt and in V8.

Solution

we see this using Bentley's hpgl2 or hpglrtl drivers. Try editing the following variable to fix.
Enable Path Support = false
Enables or prevents the printing system from using path output geometry. You may want to set this property to False when using the HPGL2 or HPGLRTL printer drivers to print to an older printer that cannot accept paths. If this property is not defined, the printing system sets it according to the capabilities of the printer driver.
