Some of the print data is dropping out. What should I check for?
Data drop-out is usually caused by the handshaking mismatched that results in problems related to the printer's receive buffer. An incorrect cable could cause this symptom as well.To check the handshaking, proceed as follows:
Prepare a large quantity of print data, and then begin transmission to the printer. Open the printer cover while printing is in progress (so that the printer goes offline) and make sure that data transmission stops. (If transmission continues, you can conclude that handshaking is not operating correctly.)
