How to use Multi-threading process for printing

I am not very familiar with multi-threading. I need help with multi-threading the ProcessStartInfo for printing to allow my .pdf files that I send to the printer to print in order. I feel that if I use multi-treading that it would allow me to print larger pdf files in the particular order that I need.

Currently was the print jobs get to the printer they tend to print off by size. I have some pretty large pdf file...

I also need to print on one side of paper. The printer is defaulted to double-sided. I want to print one-sided only for these documents...

For x As Integer = 0 To enclosureList.Count - 1
                Dim psInfo As New ProcessStartInfo

                With psInfo
                    .UseShellExecute = True
                    .Verb = "print"
                    .FileName = enclosureList(x)
                    .WindowStyle = ProcessWindowStyle.Hidden
                    Process.Start(psInfo)
                End With
 Next

@louisfr
your code worked as for as building with no errors but the order that it prints is way off. each enclosureList may have anywhere from 2 to 8 pages of enclosures including the attached word file that is a cover sheet that I insert at enclosureList(0) and then the following enclosures should follow. It is now printing (0) in-between the next enclosureList.

I placed your code at the very end of my print sub...

Should I be calling this sub differently?

I hadn't understood you had that code called on several lists.
It's the whole code which you must put inside the Thread, not just the printing of one list.
