I have a custom pc3 file saved on my hard drive for a HP 1050C plotter. I specified when I set up the file that the default paper size should be 30x42. However, when I go to plot and select the desired 1050C.pc3 device, the paper size is shown as "Previous Plot (30x42)". This causes the default paper size in the .pc3 file to go to 8.5"x11". I then must edit the settings for the .pc3 file to get the correct sheet size again. Is there any way to prevent it from using the "Previous Plot" setting??
