Here is a snippet of code that we used to validate that we could talk to a 
cash drawer:

FQSysPrt   O    F  132        Printer OflInd(*InOF)
D PrtString       S              3    Inz(x'030107') 
C                   Except    DoPrint 
C                   Eval      *InLR=*On 
OQSysPrt   E            DoPrint        1 
O                       PrtString            3 

This is probably a poor way to do it, but we just create a PC printer 
session with Client Access, do an OVRPRTF to point the spooled file to the 
PC printer and run this little program.  The printer device is a 3812 m1. 
Giving credit where credit is due, Paul Tykodi explained how to use ASCII 
transparency:

"Another way to accomplish the same task is to use the OS/400 feature 
called ASCII Transparency (ATRN). This operating system feature is the tool 
that allows the Client Access Virtual Printing and the Host Print Transform 
functions to operate correctly. The SCS hex code 03 followed by a count 
byte is the ATRN command. It tells the OS/400 operating system how many 
bytes of ASCII data are following its occurrence. 

If for example you wanted to send the HP PCL command for portrait from an 
RPG field, you could code the following values (in hex) into the field 03 
05 1B 26 6C 30 4F. The AS/400 operating system would move the information 
to the target printer for you, without interrogating it for data integrity, 
because it would already know that it was ASCII formatted data.

If you want to get creative and pass large amounts of ASCII data in this 
fashion, you need to insert the values 03 FF into your ASCII file at 255 
byte intervals."
