I've got a client that recently upgraded all their PCs from Win98 to WinXP Pro. Since this change, they are able to plot just fine to their Oce TDS600, but when they print to their HP 4MV, then their line weights are all wrong. Since only the desktops changed, is this a font issue or something else? I'm not very familiar with the Autocad 2004 product. Thanks for the help.
