I'm having an odd problem with a wrapper I've written for the PrintJob class.
One of the methods of the wrapper, printString(), takes a string of arbitrary
length and is *supposed* to print all of it, breaking it over pages as needed.
It *almost* works, and I need some assistance figuring out where the real
problem is. Here's how it works now:
1. start the printJob so we have access to pageWidth and pageHeight
2. create a temporary TextField with the dimensions of pageWidth and
pageHeight, with multiline and wordWrap on, all other settings as default
3. put the string into the TextField
4. get the number of pages and number of lines per page by setting scroll=1 and
checking bottomScroll and maxscroll
5. add enough newline padding to the end of the string so that the last page
can scroll up high enough
5. for each page:
a. set scroll = loopIndex * linesPerPage + 1
b. addPage( tempTextField )
6. send the printJob to the printer
Sound good? Good. Now, when I look at my temporary text field on screen, I see
that, with my printer settings and default formatting, 50 lines are visible on
screen at a time. *However* when I look at my printouts, I get 55 lines per
page! (This is a problem because the code *thinks* only 50 lines fit on a page,
so the pagination goes screwy.) Oh, and this happens even if I printAsBitmap.
Is there an alternate approach I'm missing? Is the size difference between
screen and print text linear? Should I be fooling around with different
TextFormats to try applying to my temporary TextField? I welcome any
suggestions.
