I would like to be able to look at the information in the
PrinterExtendedData portion of the current Preference-chosen
printer driver.
My question is: Is there a way I can get to this data (through
several levels of indirection) from the pointer returned to me
by an OpenDevice("printer.device") command? The only other way
I can think of is to ask Intuition for Preferences info, look at
which printer is chosen, LoadSeg the printer driver, and get to
it that way (ughh).
Please reply by email. I get the distinct impression that this
is an easy question, but I sure can't seem to find the answer
in my RKM. If enough of you give me an indication that this is
a non-trivial question, I'll post a summary of the answers.
My project is to modify the program which catches all calls for
DumpRPort (the name of the author escapes me) so that besides
letting you change the arguments, it will suggest some intelligent
alternatives based on the resolution of the printer being used.
I CRAVE better printer output!
While I'm on the subject, another possible solution that I can think
of for better graphic text output is to crop all the vertical rows
of dots from the RIGHT side of the picture that need to be removed
rather than every so often in the middle of the picture. I don't
mind knowing that part of my DPaint screen will not print out
(and planning for that) so long as the part that does print out is
pretty :^). In fact...
#define WISH_LIST
I would love it if every graphics program gave me the option to
work in a drawing window whose resolution is a multiple (or factor)
of the current preference printer's resolution. Or, let me finish
my masterpiece on a full screen, but show me a preview of what the
printer.device will do to it and let me doctor it up before it gets
sent to the printer. Are any of these ideas feasible, or am I
missing something?
#undef WISH_LIST
BTW, I have been a silent listener on this net for a long time and I
really appreciate everything all of you have contributed.
