S Self Test
S PRINT TEST 1 (see Chapter 1.8 Print Tests)
S PRINT TEST 2 (see Chapter 1.8 Print Tests)
S PRINT TEST 3 gives information about technical releases and is intended
for service purposes only. Among other information, the
page counter identifies the number of pages printed.
S I/F Test This function is used to test the serial interface. It enables
test data to be sent out from the printer and returned by
means of a closed loop connector plugged into the serial
interface connector. The test data uses consist of PRINT
TEST 1.
S Hex 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.
