On the left side of the printout all the codes are printed in
hexadecimal format. On the right side of the printout all
printable characters are printed, and others, such as control
codes, are represented by dots.
To turn off the data dump mode after you have taken the printer
off line, turn off the printer.
By comparing the characters printed in the text field on the right side
of the data dump printout with the printout of hex codes, you can
check which codes are being sent to the printer.
To interpret the data dump printout, examine the first three hex
codes on the second line of the printout sample (20 20 54). Each hex
code 20 represents a space; hex code 54 represents the letter T. Check
the second line of the text field on the right side of the printout and
you will find the letter T preceded by two spaces.
The chart below interprets the first eight codes.
