I would like to know if it's possible to hook multiple serial printers to one computer. That way I don't have to swap out forms when I need to print a different form

Are we talking about USB-connected printers or printers that connect using a serial port.

In either case, it is, indeed, possible to connect multiple printers to one computer. Each printer has to be plugged into its own serial port if it's a serial printer (those are pretty rare nowadays). USB-based printers can sometimes be plugged into a USB "hub", but I've had trouble with those so I recommend that each one be plugged into a separate computer port.

It can be possible with the USB ports or USB hub. With one USb hum there will be many usb prots where you can plug in your printer as you need.
