Actually, Word calls GDI to render the document, and that is trapped by
Citrix, compressed and sent down the stream. The PS / PCL is generated by
the local printer driver. Of course, if you have giga bytes of bitmaps, a
slow link will not be much good (same problem if you have splash screens
with huge bitmaps - though these are often cached on the client side by
Citrix).

You can map local disks to the server that is only valid for the session.
Its quite transparent.

If you run the windows (95/NT) client, or the browser client, video drivers
are not an issue because everything goes through the GDI / browser.
However, if you run the DOS client, you will need to be careful.
Essentially, I have only managed to get it running in 800 x 600 mode.
