Well, I prefer the Network option as it cuts out the multiple USB cords and close proximity required for multiple printers. For using the network to access those printers on your intranet, download the LPR.device file (lpr-device.lha I believe) from OS4Depot.org. Follow its simple instructions and for each printer, save an ENV:Lpr.device set tho each printer's IP address; then to change printers, copy that file to ENV: becore printing. The contents should look like, "192.168.0.125 RAW" -- I do this in an Xicon script.
For USB I will answer tomorrow morning; time for sleep.
