Check out MS KB article Q252607. It reports this exact problem with respect to the CopyFile method of the FileSystemObject. Since this is a wrapper to the underlying WinAPI fucntions. it stands to reason that the problem exists there.

MS recommends you rename the printer as you did.

>>Try:
>>
>>IF CopyFile('c:\temp\test.txt',['\\servername\printer name'],0) # 0
>>
>>This will pass everything inside the [] to the CopyFile function. Maybe it will work (can't test it from my current location).
