Chapter 11: Printer 

 
See Chapters 8, 9 and 10 for instructions about how to print out tests from the Welch Allyn OAE 
Hearing Screener. 
 
The Welch Allyn OAE Hearing Screener 29400/29401 (blue label) is only compatible with the 
Seiko label printer supplied by Welch Allyn.  The screener uses serial communication to print test 
results using the label printer.  USB printing from the screener to the label printer is not possible. 
 
Some models of Seiko label printers are only compatible with a newer version of the firmware that 
is installed on the OAE Hearing Screener using the WA OAE Load Software.  This means that the 
Seiko printer provided with a new system purchase may not print when connected to a previously 
purchased Welch Allyn OAE Hearing Screener system.  To resolve this issue, the user can 
update the firmware version installed on the older OAE Hearing Screener, using the WA OAE 
Load Software provided with the new system or printer.  Refer to Chapter 13 for instructions about 
how to install the firmware. 

 

Operating Steps 

 
1.  Connect the white power supply to the back of the Seiko label printer and plug into wall outlet. 
2.  Turn Seiko label printer on by pressing white button (green light should display). 
3.  Place white cylinder thru roll of labels.  Labels should be facing downward.  Feed label thru 

into slot behind and below the label roll container. Press the white Label feed button to start 
the label roll. 

4.  Connect the serial cable to the printer (telephone jack) and to the OAE Hearing Screener (red 

connector). 

5.  See chapter 8, 9 and 10 regarding how to print data.
