Hi EricLopez-1611,
Switching the printer to TCP/IP should not require a reinstallation of the printer or driver. I have recently done this with a USB printer to TCP/IP and it was seamless when searching for the printer. You will however, need to configure each PC to see the printer via TCP/IP.
I would suggest that you have prints stuck in the print spooler and that's why no one else can print to it at the moment.
My recommendation would be to set up the printer as TCP/IP so that all users can print to it directly and install it easily.
