I had a PRINTER subroutine or suchlike that accessed a printers file with all the parameters. Any programatic (or user command line) attempt to access a printer was via my stuff, that checked this file, and set things up accordingly. So as far as eg accounts was concerned, they had the ACCOUNTS printer. Whenever anything changed, I simply changed the ACCOUNTS entry in the parameter file. Very useful, because on the odd occasion when a printer went down I just made a temporary change to the file and everything got diverted :-) If tyou're interested, let me know and I'll see if I can find the code - I know I had it but it's a long time ago ...
