Some network users are reporting that ACAD freezes when trying to plot to our HP1050C's. All who report this problem have a Dell OptiPlex GX150 computer. Processor 1GHZ (Fiber Channel), >256 MB Ram, 16MB-TNT2 Graphics Card, functioning in a Windows 2000 (service pack 4) environment. Note that this is when PLOT PREVIEW is selected. Preview screen is generated, and drawing displayed, but no cursor is visible. Ctrl+Alt+Del does not work and a hard boot is required. Users are able to plot if they do not select the plot preview screen. Anybody have a similar problem?
