On the printout's left side, the codes are printed in hexadecimal
format. On the right side, printable ASCII characters are printed
normally, but non-printable control codes (00 to 1F hex) are
portrayed by dots.
4. To cancel the data dump mode, press the ON LINE button to set
the printer off line. Then turn off the printer.
By comparing the characters printed in the text field on the right
side of the data dump printout (see Step 3) with the printout of
hex codes, you can check which codes are being sent to the
printer. If characters are printable, they appear as their true ASCII
characters. Non-printable codes, such as control codes, are
represented by dots.
