You can think of emulation modes as printing protocols (really languages that control how output is created) that the printer supports. From the specifications
for your printer, you could use several emulation modes: PCL 5c, PCL6, PostScript. So even though there is no specific Linux driver for that printer, you could use generic PCL or PostScript drivers.
To do this, run system-config-printer (as root), then when you create the new printer, select "Generic" as the printer in the panel that says "Select Printer from database". You will then see choices for PCL 5c, PCL 6, and PostScript (among others), which you can try and see how well each one works for you.
Alternatively, if you have the Windows driver you could try using the PPD file, if any, that comes with the Windows driver. There is an option "Provide PPD file" in the same panel where you select the printer.
