I just replaced my old HP5si printer at my office because the repair cost was too much. Our new office printer is a HP8150N. My problem is that the new printer doesn't want to let my lines merge option work. I tested the printer through a system printer and set up a pc3 with the system printer option and in neither instance can I see my line through a shade. I was able to see through my shades with the HP 5si and I didn't have to worry about setting the draworder of the shaded line to back. My ctb files are the same as before, the only variables that have changed are the printer and its drivers. We are running win 2000 on the workstations and use ADT 3.3. The printer is set as a network printer. Our server is running on Linux and we use the CUPS module version 1.1.17. My questions are: Has anyone run into this problem? Is there a setting that I am over looking? Is there a hdi driver that works with ADT and the HP 8150n that I can download? I will keep trying to resolve this issue and thank you for your suggestions and help.
