Printers are odd beasts. At first glance they appear to be a bitmap printing engine for paper (or whatever the medium) and you send it a bitmap and maybe some settings. But no, they actually have a front end computer that speaks one or more page layout languages. That language tells the printer how to render the data into bitmap which is printed. You first have to figure out which language your printer speaks. If it speaks a common language like postscript (basis for PDF) or PCL (printer command language) then you might be able to use a generic driver or one from a similar printer. If it is proprietary you will need to reverse engineer it by installing the printer in a native environment along with tools to sniff/log the communications send some test prints with magic data and figure out the command language that way. Given that your printer already has a 32 bit driver it stands to reason you could have a look at the 386 source and see what fails to build on an amd64 machine. Then correct that and you have a driver.
