Final Width = 215mm
—Section 3), the printer will not be set
up when starting to print for the first
time.
The possible responses are shown on the
diagram. They are updated automatically as
the printer status changes. When operating
correctly, the printer will print a character-set
continuously until the EXIT screen key is
pressed.
If the reported status of the printer interface
does not match the known physical status, then
this implies a failure. It is possible to diagnose
the defect source by checking a second printer
unit on the same 9500B, or the same printer
unit on a different 9500B. Rectification may
require access to the internal circuitry of the
9500B or printer unit, so no further user action
is recommended, except for obvious setup
errors. Otherwise it is advisable to report the
result to your Fluke Service Center.
EXIT returns to the Interface 'Select test' menu
screen.

8.4 Printing Selftest Results
The results of All and Fast selftests can be
printed out by a printer connected to the parallel
port J103 on the rear panel. It can also be used
to print out certificates for UUTs calibrated in
Procedure mode.
This 25 way D-Type socket is located beneath
the IEEE-488 connector on the rear panel. Its
connections are similar to the 25-way printer
port on PCs, carrying control and data for an
external printer as designated in the table.

8.4.1 Introduction 8.4.2 Parallel Port (Rear Panel)
9500B 9500B 9500B Description or
Pin No. Signal Name I/O Common Meaning
1 STROBE_L Output 1µs pulse to cause printer to read one byte
of data from data bus DO1 — DO8.
2 DO1 Output Data bit 1
3 DO2 Output Data bit 2
4 DO3 Output Data bit 3
5 DO4 Output Data bit 4
6 DO5 Output Data bit 5
7 DO6 Output Data bit 6
8 DO7 Output Data bit 7
9 DO8 Output Data bit 8
10 ACKNLG_L Input Pulse to indicate that the printer has
accepted a data byte, and is ready for more
data.
11 BUSY_H Input Printer is temporarily busy and cannot
receive data.
12 P_END_H Input Printer is out of paper.
13 SLCT_H Input Printer is in online state, or connected.
14 AUTO_FEED_L Output Paper is automatically fed 1 line after printing.
This line is fixed _H (high) by the 9500B to
disable autofeed.
15 ERROR_L Input Printer is in 'Paper End', 'Offline' or 'Error'
state.
16 INIT_L Output Commands printer to reset to power-up
state, and in most printers to clear its print
buffer.
17 SLCT_IN_L Output Commands some printers to accept data.
This line is fixed _L (low) by the 9500B.
18-25 0V_F Output Digital Common
Pin Designations
_H ≡ Logic-1 active; _L ≡ Logic-Ø active.
