How to print correctly
Problem Recommendation
The printer prints unexpectedly
or it prints garbage.· Make sure the printer cable is not too long.  We recommend you
use a parallel cable of less than 2 metres (6.6 feet) in length.
· Check if the printer cable is damaged or broken.
· If you are using an interface switching device, remove it and
connect your computer directly to your printer and try again.
· Check that the appropriate printer driver is selected as ‘Set as
Default’.
· Check that the printer is not connected to the same port which is
also connected to a mass storage device or scanner.
Remove all other devices and connect the port to the printer
only.
Turn off printer status reporting in the device options tab in the
printer driver.
