Autocad error Plotter out of memory or only partial drawing is plotted solved

If you are using a Windows System Plotter driver, you can configure it to use virtual memory on the computer.

To access the settings

On the Start menu (Windows), click Settings > Printers.
Right-click the plotter and click Properties.
Set the driver to Process Document In Computer. This will process the entire plot at the computer.

The procedure for setting the driver to Process Document In Computer varies by operating system and driver.

Note: If this method does not cause the full drawing to be plotted, it is possible that the plotter does not have enough memory to hold the entire plot. For troubleshooting purposes, send a smaller size plot to the plotter (an A size plot is much smaller than an E size plot of the same drawing, for example). If the smaller plot is successful and the larger version is missing data, the plotter most likely does not have enough memory to hold the plot.
Method 2

Add memory to your plotter.

Methode 3
