toner | high contrast , black-and-white map tiles

It seems that there are limits to the WinAPI, as mentioned in the comments.

Because the previous printer is dead now, we bought a TSC ME240. There is a programming manual for TSPL/2 commands in this link.

To solve the problem i connected the printer to the network and send TSPL/2 commands through a tcp socket.

I needed this code to get the status

You need to set the color for the NA values used in geom_tile. To do that, add a line scale_fill_continuous(na.value = NA).

To make your loop work (with modern browsers), use the let keyword to define the path:

The problem might be that geom_voronoi_tile expects the voronoi polygons to be closed, and your dataset lacks the outer boundaries. A quick alternative is to fall back to ggvoronoi::geom_voronoi().

When we change codes that way it works, it throw error because after addrange categories and product, i have to run savechanges() because products and categories have to get id's from database after that we can mark productcategory.

SeedDatabase.cs

You had point data, not polygons.

Actually your result will be in $matches[0]:
