If you enable this option, you can print posters of different sizes " " The printout will happen in the form 'tiles' printed on smaller " " paper sizes, which you can stitch together later. If you enable this " " option here, the 'Poster Printing' filter will be auto-loaded in " " the 'Filters' tab of this dialog.

" "

This tab is only visible if the external 'poster' utility is " " discovered by KDEPrint on your system. ['poster' is a commandline " " utility that enables you to convert PostScript files into tiled printouts " " which allow for oversized appearance of the stitched-together tiles.]

" "

Note: The standard version of 'poster' will not work. Your system " " must use a patched version of 'poster'. Ask your operating system vendor to " " provide a patched version of 'poster' if he does not already.

" "

Additional hint for power users: A patched version of 'poster' is " " available from the KDEPrint Website " " at http://printing.kde.org/downloads/. " " The direct link to the patched source tarball is " " ftp://ftp.kde.org/pub/kde/printing/poster.tar.bz2 " "

" " " ); QString whatsThisTileSelectionPosterPage = i18n( " " " Tile Selection widget " "

This GUI element is not only for viewing your selections: it also " " lets you interactively select the tile(s) you want to print. " "

" "

Hints " "

    " "
  • Click any tile to select it for printing.
    • " "
  • To select multiple tiles to be printed " " at once, 'shift-click' on the tiles ('shift-click' means: hold down the " " [SHIFT]-key on your keyboard and click with the mouse while [SHIFT]-key is held.) " " Be aware that the order " " of your clicking is also significant to the order of printing the different tiles.
    • " "
" " Note 1: The order of your selection (and the order for printout of the tiles) " " is indicated by the contents of the text field below, " " labelled as 'Tile pages (to be printed):'

" " Note 2: By default no tile is selected. Before you can print (a part " " of) your poster, you must select at least one tile.

" " " ); QString whatsThisPostersizePosterPage = i18n( " " " Poster Size " "

Select the poster size you want from the dropdown list.

" " Available sizes are all standard paper sizes up to " " 'A0'. [A0 is the same size as 16 sheets of A4, or '84cm x 118.2cm'.]

" "

Notice, how the little preview window below changes with your change of poster " " size. It indicates to you how many tiles need to be printed to make the poster, " " given the selected paper size.

" "

Hint: The little preview window below is not just a passive icon. You can click " " on its individual tiles to select them for printing. To select multiple tiles to be printed " " at once, you need to 'shift-click' on the tiles ('shift-click' means: hold down the " " [SHIFT]-key on your keyboard and click with the mouse while [SHIFT]-key is held.) The order " " of your clicking is significant to the order of printing the different tiles. The order of " " your selection (and for the printed tiles) is indicated by the contents of the text field " " labelled as 'Tile pages (to be printed):'

" " Note: By default no tile is selected. Before you can print (a part " " of) your poster, you must select at least one tile.

" " " ); QString whatsThisPrintsizePosterPage = i18n( " " " Paper Size " "

This field indicates the paper size the poster tiles will be printed on. " " To select a different paper size for your poster tiles, go to the 'General' tab " " of this dialog and select one from the dropdown list.

" " Available sizes are most standard paper sizes supported by your printer. Your printer's " " supported paper sizes are read from the printer driver info (as laid down in the 'PPD', " " the printer description file). Be aware that the 'Paper Size' selected may not be supported " " by 'poster' (example: 'HalfLetter') while it may well be supported by your printer. If " " you hit that obstacle, simply use another, supported Paper Size, like 'A4' or 'Letter'. " "

Notice, how the little preview window below changes with your change of paper " " size. It indicates how many tiles need to be printed to make up the poster, " " given the selected paper and poster size.

" "

Hint: The little preview window below is not just a passive icon. You can click " " on its individual tiles to select them for printing. To select multiple tiles to be printed " " at once, you need to 'shift-click' on the tiles ('shift-click' means: hold down the " " [SHIFT]-key on your keyboard and click with the mouse while [SHIFT]-key is held.) The order " " of your clicking is significant to the order of printing the different tiles. The order of " " your selection (and for the printed tiles) is indicated by the contents of the text field " " labelled as 'Tile pages (to be printed):'

" " Note: By default no tile is selected. Before you can print (a part " " of) your poster, you must select at least one tile.

" " " ); QString whatsThisCutmarginPosterPage = i18n( " " " Cut Margin selection " "

Slider and spinbox let you determine a 'cut margin' which will be printed onto " " each tile of your poster to help you cut the pieces as needed.

" "

Notice, how the little preview window above changes with your change of cut " " margins. It indicates to you how much space the cut margins will take away from each tile. " "

Be aware, that your cut margins need to be equal to or greater than the margins your " " printer uses. The printer's capabilities are described in the 'ImageableArea' " " keywords of its driver PPD file.

" " " ); QString whatsThisTileOrderSelectionPosterPage = i18n( " " " Order and number of tile pages to be printed " "

This field displays and sets the individual tiles to be printed, as well as the order " " for their printout.

" " You can file the field with 2 different methods: " "
    " "
  • Either use the interactive thumbnail preview above and '[SHIFT]-click' on the tiles.
    • " "
  • Or edit this text field accordingly.
    • " "
" "

When editing the field, you can use a '3-7' syntax instead of a '3,4,5,6,7' one.

" "

Examples:

" " 
 "
			"   \"2,3,7,9,3\" "
			" 
 "
			"   \"1-3,6,8-11\" "
