loose connection can generate meaningless characters and symbols to
print.

Is the printer port set to ECP?
When the printer port of the computer to the ECP mode, the printer may not
perform a print job properly. Cancel the ECP mode, and print again.
If the problem is not solved, contact a hardware manufacturer.
Check 5
Is the problem in the original file?
If meaningless character or symbols are printed only when you print a cer-
tain file, the cause of the problem may be in the file or the application pro-
gram you are using. Rebuild the file and print it again.
If the rebuilt file prints correctly, the original file was probably faulty.
