The problem with extending the printer cable is the added propagation delay of  
the additional length of cable.  Signals have to travel from the computer, to  
the printer, & back, so the propagation delay is related to twice the length of  
the cable.  

The system was designed to work reliably with the standard printer cable over  
all combinations of computers, printers, and specified temperatures.  Extending  
the cable will remove margin from the design, increasing the chance that you  
will get errors while printing.

If you lengthen your cable & have problems, error messages will show up on the  
console.
