I get the following error after installing iPrint on a Netware 5.1 (SP8)
server with Enterpise Web Server already installed.

conf_init: Error running init function load-modules: dlsym NsapiIppInit
failed (SEC_ERROR_INVALID_ARGS)

I followed the following instructions to modify the obj.conf file:

File 1: SYS:NOVONYX\SUITESPOT\HTTPS-<SERVERNAME>\CONFIG\OBJ.CONF

Add this AS ONE LINE to the end of the Init section ensuring
a space before "shlib=" and "fn=":

Init funcs="NsapiIppInit,NsapiIppService"
shlib="SYS:/system/ipp/ippsrvr.nlm"
fn="load-modules"

Add this AS ONE LINE to the end of the NameTrans fn="pfx2dir"
section and before the NameTrans fn="nw_home" section ensuring
a space before "dir=":

NameTrans fn="pfx2dir" from="/ipp"
dir="/system/ipp" name="IPPServer"

Add these lines to the end of the file.
<Object name="IPPServer">
Service fn="NsapiIppService"
</Object>
