When plotting from AutoCad 2004 on Windows 2000 +SP4 to HP1220c printer, the plot is not produced. The printhead shuttles around the right hand edge of the paper then moves across to the left hand edge of the paper then expels the paper without printing anything. The printer then flashes the paper feed button. Pressing the paper feed button causes the whole process to repeat. The printers are connected to the network via JetDirect boxes and the printers are shared across the network. The printer driver is V2.1, the latest from HP as recommended in the AutoCad knowledgebase. Able to print from Windows applications(Excel,Word) with no problems. The problem does not occur with all drawings. Has anyone come across this before or have any suggestions ?
