When installing iPrint printers was recieving error code 5.
Here is an old tid on this.
This is an old TID that talks about fixing this problem with Netware 5 and 6.5. The solution still applies but the iprint.ini file on a linux OES server is located in /var/opt/novell/iprint/htdocs
Changed AllowUserPrinters to 1 default is 0 which will require the user to have rights on the local computer. 1 tries to install as workstation printer, if not it installs it as a user printer, 2 just installs as user printer
