[MiNT] gemlib: printer dialog function

[Gerhard_Stoll@b.maus.de (Gerhard Stoll)]

Hello!

I import in the gemlib and tos.hyp four function with used from the printer
dialog of WDialog. Can someone check my work from the gemlib.

The function disable_nvdi_errors and enable_nvdi_errors are not in the gemlib,
because they change the NVDI cookie.
