3–41Troubleshooting

Hex Code Printout

A hex code printout (“hex dump”) lists each ASCII data character received

from the host computer and lists its corresponding two-digit hexadecimal

code. (See Figure 3–2.) Hex dumps can be used to troubleshoot some types

of printer data reception problems.

Every printable character prints both as its assigned symbol and as its hex

equivalent. Every nonprintable (ASCII control) character prints both as a

period (.) and as its hex equivalent. When using a parallel interface, the letter

“p” before a hex code indicates an active Paper Instruction (PI) line and a

blank space before a hex code indicates an inactive PI line.

To make a hex code printout, refer to the procedure on page 3–42. To convert

an ASCII character to its corresponding hex code (or vice-versa), refer to the

ASCII code chart on page 3–43.
