Raw printing only for one printer

[Bryan Maupin]

We have a CUPS server set up which is passing jobs from Windows servers to a Windows print server (don't ask me why).  The printers on the Windows print server are set up using IPP, added to the CUPS server running on RHEL 5.5, which I then set up so that the Windows servers could print to it using these instructions:

Everything worked fine, until one of the printers that was added to the Windows print server was using a TROY MICR driver.  To be honest, I'm not completely sure how all of that works, but I know that we can print fine to all printers except that one.

I've seen that it's possible to set up the CUPS print server for raw printing so that instead of the Windows print clients using CUPS drivers, they would use the actual driver for the printer and CUPS would simply pass everything through (http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/CUPS-printing.html#id2634124).  Is there a way that I can set up this one MICR printer to print raw (using the normal Windows print drivers) while leaving all the other printers the same (using the Windows CUPS print drivers)?

Many thanks.
