Hi mrkoko,
The setting is under the printer in Windows (I think). I cannot check becuase the IT Nazis have taken away virtually every thing that can be taken on our network. Amyway, I recall needing to choose using computer memory for our previous plotter to get all the lines to print (Adobe). We are now over to laser printers, and a new plotter, all with network cards built in, so this is not an issue for us any more. Do the missing lines show in print previews?
