If you only need to change the print server name there are scripts already written on the board which will do this for you - I know because I posted one a long time ago.

If you need to re-connect the printers to pick up new printer drivers then you should be able to kludge the script to do this for you with very little additional effort.

Search the board for the scripts - if you get stuck and really cannot find them then post again and we'll have a look for you.
