High resolution EEG output using a laser printer.

With increasing computerization, digitization and complexity of 64- to 128-channel long-term monitoring (LTM), new problems have arisen with data presentation. We describe customized software that allows for high resolution EEG output on a standard laser printer. This system can display from 1 to 128 channels of EEG on standard or legal size paper with freedom to alter both time and amplitude scales as desired. This technique is inexpensive and provides a high resolution rectilinear paper record of selected EEG events that is convenient for review and storage.
