I have an HP Designjet 500 plotter.
With Draftsight 2017 I was printing without problems. Now with Draftsight 2019 I can't print and I get the message "The driver plotter has not been found, the device has not been found or there is a problem with the drivers" and I have to finish abruptly with CTRL+ALT+CANC
After this attempt, the DWG files on reopening are read-only, as if they were still open by me.
The plotter prints without problems from an old version of Autocad 2004.
I ask you for assistance.
Excuse my English, I'm using a translator.
