I'm having some problems using the DumpRastPort printer command from TDI's
Modula-2. Can anyone with any experience with printing in Modula or any
other language help me with the following:
1) The code I'm using will print a rastport correctly, but when running
under any version of 1.2 it never returns from the DoIO call. It works
fine under 1.1
2) What does the colour map do in DumpRastPort? I would assume that the
entries in the map would only affect which dots were black and which were
white, but some combinations will cause the system to crash, and most
others make no sense.
3) I have been using the Epson driver, and the scaling values passed with
the DumpRastPort command appear to have no effect on the output. Is this
just this driver, or are these not implemented yet, or am I doing something
wrong?
In conclusion, I have found the printing on this machine to be very crudely
implemented and poorly documented. Can anyone point me to the appropriate
fount of information and set me straight?
