This script was published by Villeroy at the Code Snippets Forum.
- Villeroy quote
- The attached Python code provides 2 routines. One prints the current selection of (multiple) cell range(s), the other one prints the used ranges of the selected sheet(s).

Process of the script
The script perform the following tasks:
- Loop through the sheets collection and load the print ranges them in a variable.
- Remove them
- Change the selected ranges into print ranges
- Store the ranges into a temporary PDF
- Clear the print ranges
- Restore the original print ranges
Load print ranges
We start by grabbing the area from the Calc page using the com.sun.star.table.CellRangeAddress, establish the start and end of the area and return the total area.
def getUsedAddress(oSheet): '''com.sun.star.table.CellRangeAddress of a sheet's used range''' oRg = oSheet.createCursor() oRg.gotoStartOfUsedArea(False) oRg.gotoEndOfUsedArea(True) return oRg.getRangeAddress()
Clear print ranges
This function reset the cell range using the createEnumeration() function and doing a loop until the end.
def clearPrintAreas(doc): '''remove all print areas from a Calc document''' esh = doc.Sheets.createEnumeration() while esh.hasMoreElements(): sh = esh.nextElement() sh.setPrintAreas(tuple())
Create print ranges
def getPrintAreasDict(doc): '''return a dict of sheet indices with print areas''' d = {} esh = doc.Sheets.createEnumeration() while esh.hasMoreElements(): sh = esh.nextElement() n = sh.RangeAddress.Sheet d[n]= sh.getPrintAreas() return d def setPrintAreasByDict(doc, d, bWholeSheet): for k,v in d.items(): sh = doc.Sheets.getByIndex(k) if bWholeSheet: v = (getUsedAddress(sh),) sh.setPrintAreas(v)
Print as PDF
def getTmpURL(): import unohelper, os f = os.tmpnam() +'.pdf' return unohelper.systemPathToFileUrl(f)
Clear the ranges
def getDictFromAddresses(tpla): '''Split tuple of addresses into dict of sheet indices.''' d = {} for i in tpla: ish = i.Sheet if not d.has_key(ish): d[ish] = [i,] else: d[ish].append(i) for k,v in d.items(): d[k] = tuple(v) return d
