flash actionscript:
I recently had to impliment printing of the content of a textArea that was
dynamically populated. The first problem I ran into was how to access the
textArea for printing. I quickly avoided that problem by populating an off
stage text field with the same data. I placed that text field in a movie clip
so I could print that clip.
The next problem I ran into was, depending on the data, the text feild may
contain more then one page worth of printing. I search the forums for an
answer, but only found the question. So I had to come up with a way to add
multiple pages to my PrintJob based on a text field that could be any size.
Here is the script I came up with:
It is pretty simple, it check sthe hieght of the text holder clip against the
PrintJob.pageHeight. If the movieclip height is larger, It devides it by the
pageHeight to get the number of pages needed to print the whole thing, then
runs a loop to add the pages. I then used the pageHeight and mc height to get
the min and max y boundries for printing.
pageHeight*i got me the ymin, then adding the mc height to that got me the
ymax.
If the mc height wasn't larger then the pageHeight, it only adds one page.
hope this helps some of you, and I welcome any comments, changes, additions or
criticism of this script.

var mh:Number = textHolder_mc._height;
var pageCount:Number = 0;
var my_pj:PrintJob = new PrintJob();
if (my_pj.start()) {
if (mh>my_pj.pageHeight) {
var pnum:Number = Math.ceil(mh/my_pj.pageHeight);
trace(pnum);
for (var i:Number = 0; i<pnum; i++) {
var ymn:Number = my_pj.pageHeight*i;
var ymx:Number = ymn+my_pj.pageHeight;
my_pj.addPage("textHolder_mc", {xMin:0, xMax:my_pj.pageWidth, yMin:ymn,
yMax:ymx}, null, 1);
pageCount++;
}
} else {
my_pj.addPage("textHolder_mc", {xMin:0, xMax:my_pj.pageWidth, yMin:0,
yMax:my_pj.pageHeight}, null, 1);
pageCount++;
}
if (pageCount>0) {
my_pj.send();
}
delete my_pj;
