balafrus, if you look again in the manual, exist is a function.
thus it is Exist()

Code:
if exist("myfolder") or exist("myFile") or not exist("yourFile")



now, still...
you don't have kixtart 4.xx but with you can do pretty amazing stuff with 3.62 and it surely is not that old.
just lacks some of the cool newer functionality.

if you can't tell the naming schema (if there is any) for the printers, can't assist you further.

in your attempt in the first post of yours, you just write the reg-value but there is lot more than reg-value to having a printer connected.
thus, use kixtart's inbuild AddPrinterConnection() instead.
