Contol Escape in vi editor

Control Escape is a special charecter, which used for many PCL commands, its prerry hard to copy paste these in to a vi editor directly from a html/pdf/text PCL documents.

But you can simulate this charecter in vi editor. for that press

control+v and then escape, ( press the keys in the same order donot release any of the keys till you pressed the escape ). the equivalent ASCII is '\033'.
