There is a printer driver program from Leadtools that will read in all sorts of printer format files and save them as gerber files or even dxf files. Use it to read in your text and save as dxf, then import it into your board. On the other hand you can create a small photoplot file and import it into your layer photoplot. I haven't used this for a while, so you should download their eval version and see if it does what you want. I think the eval is good for 15 or 30 days.
