    Optimizing the Printing Using Rules
    In This Topic

    Spread provides a way to automatically determine the best way to print your sheet. By using rules that you can choose, it can decide, for example, whether it is best to print your sheet on landscape- or portrait-oriented pages.

    The rules, that you can turn on or off, that optimize the printing can be customized by setting the properties of these rule objects:

    Rule Object Description
    LandscapeRule Determines whether to print the sheet in landscape or portrait orientation.
    ScaleRule Determines the best scale at which to print the sheet, starting with 100% (Start Factor = 1), and decreasing at set intervals to a minimum size (End Factor).Default settings are Start Factor = 1, End Factor = 0.6, and Interval = 0.1.
    BestFitColumnRule Determines how best to fit the columns in the sheet on the page.

    By default, optimizing the printing of the sheet uses the following logic:

    You can customize how this logic is applied through the rule objects. If you customize the rule object, the default rules are ignored and only the custom rules are used for printing. You can set up a collection of these rules with the SmartPrintRulesCollection object and set whether to use these rules with the UseSmartPrint property.

    Using the Properties Window

    1. At design time, in the Properties window, select the Spread component.
    2. Select the Sheets property.
    3. Click the button to display the SheetView Collection Editor.
    4. In the Members list, select the sheet for which to use SmartPrint.
    5. In the properties list, double-click the PrintInfo property to display the settings for the PrintInfo class.
    6. Set the UseSmartPrint property to true.
    7. If you want to customize the SmartPrint rules, select the SmartPrintRules and click the button to display the SmartPrintRule Collection Editor. Customize the rules as you want, then click OK to close the SmartPrintRule Collection Editor.
    8. Click OK to close the SheetView Collection editor.

    Using a Shortcut

    1. Create a PrintInfo object.
    2. If you want to change how SmartPrint determines how best to print the sheet, create a new SmartPrintRulesCollection object.
    3. Set the PrintInfo object UseSmartPrint property to true.
    4. Set the Sheets shortcut object PrintInfo property to the PrintInfo object you just created.

    Example

    This example code prints using customized print rules, set up in the SmartPrintRulesCollection object. In this example, if the sheet does fit on a page by shrinking columns to the longest text string, it prints with the columns shrunk. If it does not fit with the columns shrunk, it keeps them shrunk and tries to print in landscape orientation. If it does not fit with the columns shrunk and in landscape orientation, it keeps these settings and tries to scale the sheet, starting at 100%, then decreasing by 20% intervals down to 40%.

    C#
    Copy Code
    // Create the print rules.
    FarPoint.Win.Spread.SmartPrintRulesCollection printrules = new FarPoint.Win.Spread.SmartPrintRulesCollection();
    printrules.Add(new FarPoint.Win.Spread.BestFitColumnRule(FarPoint.Win.Spread.ResetOption.None));
    printrules.Add(new FarPoint.Win.Spread.LandscapeRule(FarPoint.Win.Spread.ResetOption.None));
    printrules.Add(new FarPoint.Win.Spread.ScaleRule(FarPoint.Win.Spread.ResetOption.All, 1.0f, .4f, .2f));
    // Create a PrintInfo object and set the properties.
    FarPoint.Win.Spread.PrintInfo printset = new FarPoint.Win.Spread.PrintInfo();
    printset.SmartPrintRules = printrules;
    printset.UseSmartPrint = true;
    // Set the PrintInfo property for the first sheet.
    fpSpread1.Sheets[0].PrintInfo = printset;
    // Print the sheet.
    fpSpread1.PrintSheet(0);
    
    VB
    Copy Code
    ' Create the print rules.
    Dim printrules As New FarPoint.Win.Spread.SmartPrintRulesCollection()
    printrules.Add(New FarPoint.Win.Spread.BestFitColumnRule(FarPoint.Win.Spread.ResetOption.None))
    printrules.Add(New FarPoint.Win.Spread.LandscapeRule(FarPoint.Win.Spread.ResetOption.None))
    printrules.Add(New FarPoint.Win.Spread.ScaleRule(FarPoint.Win.Spread.ResetOption.All, 1.0F, 0.4F, 0.2F))
    ' Create a PrintInfo object and set the properties.
    Dim printset As New FarPoint.Win.Spread.PrintInfo()
    printset.SmartPrintRules = printrules
    printset.UseSmartPrint = True
    ' Set the PrintInfo property for the first sheet.
    fpSpread1.Sheets(0).PrintInfo = printset
    ' Print the sheet.
    fpSpread1.PrintSheet(0)
    

    Using Code

    1. Create a PrintInfo object.
    2. If you want to change how SmartPrint determines how best to print the sheet, create a new SmartPrintRulesCollection object.
    3. Set the PrintInfo object UseSmartPrint property to true.
    4. Set the SheetView object PrintInfo property to the PrintInfo object you just created.
