.net - WPF Printing Large Report Causes OutOfMemoryException -

i've created fixeddocument study printed monthly. average 350 pages in length half pages beingness ~200kb jpeg images. study displays nicely in documentviewer, nail problems when attempting print it.

when using

documentviewer1.print()

if seek , print first 3rd of months info eg. 120 pages, works fine. if seek whole month, @ 160th page next error

i thought i'd outsmart printing 30 pages @ time splitting document little 30 page documents using:

dim dlg = new printdialog() if dlg.showdialog() = true dim pagecounter int32 = 0 dim listofdocs new list(of fixeddocument) dim currentfixeddoc new fixeddocument each fixedsizepag fixedpage in printlistofpages dim fixedsizedpageconten pagecontent = new pagecontent ctype(fixedsizedpageconten, iaddchild).addchild(fixedsizepag) currentfixeddoc.pages.add(fixedsizedpageconten) pagecounter = pagecounter + 1 if pagecounter >= 30 listofdocs.add(currentfixeddoc) pagecounter = 0 currentfixeddoc = new fixeddocument end if next if currentfixeddoc.pages.count > 0 listofdocs.add(currentfixeddoc) end if each docum in listofdocs dlg.printdocument(docum.documentpaginator, "testing - part " & (listofdocs.indexof(docum) + 1) & " of " & listofdocs.count) next end if

but caused same error. i've tried printing hundred pages midpoint , towards end of month , works, must volume of pages rather particular image(images jpegs 1 source, max size 400kb).

watching amount of memory beingness used while printing 30 pages @ time see

start = 96mb 30 pages = 367mb 60 pages = 588mb 90 pages = 825mb 120 pages = 1003mb 150 pages = 1238mb

then crashes on next batch @ 1281mb

i've tested on real printer , xps windows printer. when noted downwards memory values, waited until each section had spooled , printed.

i can't understand why building when i'm splitting them separate individual documents. must have dispose i'm not sure what?

you should generate 10 pages per file (a fixeddocument per file), merge these files 1 (you have fixeddocumentsequence). next print on fixeddocumentsequence. sure solution consumes no much memory.

system.windows.xps.xpsdocumentwriter.write(system.windows.documents.fixeddocumentsequence fixeddocumentsequence)
