If they are defined on the servers as shared and you are printing thru the servers you can use kixtart to add all the printers. for example
kix32..bat has v:\kix32.exe v:\kix2 (v drive is shared drive)
i.e. in kix2.kix file:
We have all of our printers defined in the .kix file and we blast in 50 printers all at once this way. Probably a better way to do it but this is a simple way and it works.
Note you can delete printers also with kixtart.
