Use the SHELL command. In the VBE, type in the word SHELL, move the cursor
onto the word, then hit the F1 key to get the Help documentation for it.

For your situation (and a nod to Steve Yandl for the idea) I think this may
work:
....
Shell "CSCRIPT %windir%\system32\prnmngr.vbs -ac -p" & Chr(34) &
"\\rds1\Printer088" & Chr(34)
....
The Chr(34) is for placing the quotes around the printer location.
