You can use APRINTERS() to check if any printers are installed and start AddPrinter Wizard if necessary. Code below shows how to do that using WSH but you can use your favorite method of running external programs.

oShell = Createobject("wscript.shell")
oShell.Run("%windir%\\system32\\rundll32.exe printui.dll, PrintUIEntry /il")

>When I issue the command getprint () and there is no printer
>installed, I see the message "printer not ready"
>
>Is it possible to call printer installation wizard, when this error
>happens ?
