If you add more memory and you still receive a Mem Overflow
message, change the Page Protect setting in the printer driver;
see "Using the EPL-N2000 Driver" in Chapter 2 for details. (If
you are using the Windows 3.1 EPSONScript driver, change the
setting on the control panel as described in "Config Menu" in
Chapter 3.) You can also add even more memory, or print at 300
dpi instead of 600 dpi.
