PrintDlgEx and collated printing
I'm trying to do a version of collated duplex printing on a plain one-sided non-collating printer (any printer).
.
In english ...
...I want to print many copies of a multi-page document.
...I want to print double sided ie both sides of the paper.
...I want each document to remain in order so I don't have to sort it out at the end of the print run.
...I want the application to wait for the user to take the 'half-printed' document (ie one side printed so far) and
place it in the paper tray so the printer will proceed to print on the 'other' side (ie non-printed so far).
.
For example I want to print 2 copies of a 10 page document.
.
My pseudo code (based on my current 'non-standard' MFC code) is :
.
// Code starts here ..
> Do twice // Two copies
> {
> Print pages 1,3,5,7,9 in that order // print 'odd' pages ie side 1 of paper
> }
> {
Stop and ask user to get the 'just printed' paper and put back in paper tray. Orient the paper so the printer will
print on the 'other' (un-used) side of the paper.
> }
>
> Do twice
> {
> Print pages 10,8,6,4,2 // print 'even' pages ie side 2 (unprinted)
> } // Print in reverse order - that is the way
> // they came out of the printer (hopefully)
> // ie Print page 10 on back of page 9
> // print page 8 on back of page 7 etc ...
>
// code ends
.
Having read a little in this great site I believe I must derive a class from CPrintDialog and CPrintInfo to accomplish
this task.
.
I have found some minimal documentation (and NO sample code sob, sob ) on PrintDlgEx. It seems to me that I must
replace the standard CPrintDialog and OnFilePrint routines. Is there any sample code around for PrintDlgEx?
.
The bottom line questions are:
.
....How do I print every second page in a document?
....How do I ask for user intervention in the middle of a print run?
....How do I print from the end of a document forwards every second page?
.
At the moment I have code that does all of the above but in a 'non-standard MFC' way. Is there any 'standard' MFC way
of accomplishing the above goals?
.
Another question that spans Global Variables and Printing ...
... In the MFC source code in VC6 the CPrintingDialog class uses a 'global' (I suppose) variable bUserAbort in
_afxWinState. What, where, and why is _afxWinState? I could not get it to 'work' so I supplied my own global variable
and it worked perfectly ie sends the 'cancel print' button state to the underlying print job.
.
Any ideas would be appreciated.
