Printing PS3 on Brother DCP6690CW

Hi all!

Thanks for reading this! Am really not sure whether this is the right forum for such a query...

Getting straight to the point, my issue is the following:

I am part of an organisation where we use an operating system called Advantage Windows (By GE Healthcare) for use with MRI and CT Scan machines. We had, until recently, outsourced all of our colour printing to a company who had a xerox printer + linux workstation to do all of our colour printing. Since they were basically charging a bomb, and their service sucked, we decided to chuck them and get our own printer. Subsequently, I got the Brother DCP6690CW printer, with a refillable ink tank. Print costs drastically decreased. The problem is that the Advantage Windows Workstations can only print to a PostScript 3 printer, which the Brother is not. So right now, one has to export the images that need to be printed onto a pen-drive, and give the print from a nearby windows computer. Even though this is not particularly tedious, I would want to know whether its possible to print PS3 data on the Brother DCP6690CW? Right now it is directly connected to the office WIFI without any one PC acting as a server. I feel that there must be some way to print this data by using a PC as a server or something.

Any help would be greatly greatly appreciated!

Thanks!
