This problem usually occurs when there is a buffer overrun. Manifest printing uses the printer's graphics commands to accommodate font spacing. In this mode, the printer receives a great deal more data than is required for a simple text document. In most cases this is usually caused by inexpensive network printer adapters that are unable to handle the volume of data. If the printer only supports a Centronics parallel cable, use a multi-parallel port card in an older PC system and configure it to support print sharing to support network printing.
