Logon printer script error

I have made a vbs printer script that adds printers when a user loggs on, and we have 2 workstation that have physically attached printers that we have shared out. These printers are included in my logon printer script. On the workstations that have no printer attached then the script works fine with no errors. But when the workstations that have the printers attached try and run the script or when they logon then it comes up with a printer script error:

Script: target of the script..
Line:20
Char:1
Error: The filename, directory name, or volume label syntax is incorrect.
Code:8007007B
Source: (null)

Now if you see the code snippet i was logging into workstation2 which has a printer attached with a share name of HP2200_Admin.

So im wondering if there is a way so that no script errors occur no matter what computer you are logging into.
