TEST 1.

SHex Dump

This function makes it possible that the data received by the printer can be analyzed. Control codes are no longer carried out, instead all data is printed in hexadecimal format and as ASCII characters. Any non-printable characters, such as carriage return are only represented as a single dot (.) in the ASCII list.

It may happen that the transmission of data to the printer will be interrupted during Hex Dump. In this case, printing of data received after the break is started on the next available line. The result is an irregular right margin which is not an indicator for any loss of data.
