In the DYMO Label Software v8, you go to edit > preferences > labelWriter printer and select 'text' as print quality to reduce print quality which increases print speed.
However, how do I do this when sending a label to the printer from my VB.Net app using the SDK?
A dymo developer answered my question on the DYMO Developer website:
You can use the LabelWriterPrintParams class to set the graphics mode that adjusts the printed resolution.
Basically, the following lines will do the trick for vb.net:
Dim printParams As LabelWriterPrintParams = New LabelWriterPrintParams
printParams.PrintQuality = LabelWriterPrintQuality.Text
Label.Print(printer, printParams)
