Setting Print Options with Node.js via C++

Microsoft Excel’s page setup settings provide several print options (also referred to as sheet options) that allow users to control how worksheet pages are printed.

Setting Print Options

These print options allow users to:

• Select a specific print area on a worksheet.
• Print titles.
• Print gridlines.
• Print row/column headings.
• Achieve draft quality.
• Print comments.
• Print cell errors.
• Define page ordering.

Aspose.Cells for Node.js via C++ supports all the print options offered by Microsoft Excel and developers can easily configure these options for worksheets using the properties offered by the PageSetup class. How these properties are used is discussed below in more detail.

Set Print Area

By default, the print area incorporates all areas of the worksheet that contain data. Developers can establish a specific print area of the worksheet.

To select a specific print area, use the PageSetup class' PageSetup.getPrintArea() property. Assign a cell range that defines the print area to this property.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Obtaining the reference of the PageSetup of the worksheet
const pageSetup = workbook.getWorksheets().get(0).getPageSetup();

// Specifying the cells range (from A1 cell to T35 cell) of the print area
pageSetup.setPrintArea("A1:T35");

// Save the workbook.
workbook.save(path.join(dataDir, "SetPrintArea_out.xls"));

Set Print Titles

Aspose.Cells allows you to designate row and column headers to repeat on all pages of a printed worksheet. To do so, use the PageSetup class' PageSetup.getPrintTitleColumns() and PageSetup.getPrintTitleRows() properties.

The rows or columns that will be repeated are defined by passing their row or column numbers. For example, rows are defined as $1:$2 and columns are defined as $A:$B.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Obtaining the reference of the PageSetup of the worksheet
const pageSetup = workbook.getWorksheets().get(0).getPageSetup();

// Defining column numbers A & B as title columns
pageSetup.setPrintTitleColumns("$A:$B");

// Defining row numbers 1 & 2 as title rows
pageSetup.setPrintTitleRows("$1:$2");

// Save the workbook.
workbook.save(path.join(dataDir, "SetPrintTitle_out.xls"));

Set Other Print Options

The PageSetup class also provides several other properties to set general print options as follows:

• PageSetup.getPrintGridlines(): a Boolean property that defines whether to print gridlines or not print.
• PageSetup.getPrintHeadings(): a Boolean property that defines whether to print row and column headings or not.
• PageSetup.getBlackAndWhite(): a Boolean property that defines whether to print the worksheet in black and white mode or not.
• PageSetup.getPrintComments(): defines whether to display the print comments on the worksheet or at the end of the worksheet.
• PageSetup.getPrintDraft(): a boolean property that defines whether to print the sheet without graphics.
• PageSetup.getPrintErrors(): defines whether to print cell errors as displayed, blank, dash or N/A.

To set the PageSetup.getPrintComments() and PageSetup.getPrintErrors() properties, Aspose.Cells for Node.js via C++ also provides two enumerations, PrintCommentsType and PrintErrorsType that contain pre-defined values to be assigned to the PageSetup.getPrintComments() and PageSetup.getPrintErrors() properties respectively.

The pre-defined values in the PrintCommentsType enumeration are listed below with their descriptions.

Print Comments Types	Description
PrintInPlace	Specifies to print comments as displayed on the worksheet.
PrintNoComments	Specifies not to print comments.
PrintSheetEnd	Specifies to print comments at the end of the worksheet.

The pre-defined values of PrintErrorsType enumeration are listed below with their descriptions.

Print Errors Types	Description
PrintErrorsBlank	Specifies not to print errors.
PrintErrorsDash	Specifies to print errors as “–”.
PrintErrorsDisplayed	Specifies to print errors as displayed.
PrintErrorsNA	Specifies to print errors as “#N/A”.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Obtaining the reference of the PageSetup of the worksheet
const pageSetup = workbook.getWorksheets().get(0).getPageSetup();

// Allowing to print gridlines
pageSetup.setPrintGridlines(true);

// Allowing to print row/column headings
pageSetup.setPrintHeadings(true);

// Allowing to print worksheet in black & white mode
pageSetup.setBlackAndWhite(true);

// Allowing to print comments as displayed on worksheet
pageSetup.setPrintComments(AsposeCells.PrintCommentsType.PrintInPlace);

// Allowing to print worksheet with draft quality
pageSetup.setPrintDraft(true);

// Allowing to print cell errors as N/A
pageSetup.setPrintErrors(AsposeCells.PrintErrorsType.PrintErrorsNA);

// Save the workbook.
workbook.save(path.join(dataDir, "OtherPrintOptions_out.xls"));

Set Page Order

The PageSetup class provides the PageSetup.getOrder() property that is used to order multiple pages of your worksheet to be printed. There are two possibilities to order the pages as follows.

• Down then over: prints all the pages down before printing any pages to the right.
• Over then down: prints pages left to right before printing the pages below.

Aspose.Cells provides an enumeration, PrintOrderType that contains all pre-defined order types.

The pre-defined values of the PrintOrderType enumeration are listed below.

Print Order Types	Description
DownThenOver	Represents printing order as down then over.
OverThenDown	Represents printing order as over then down.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.Workbook();

// Obtaining the reference of the PageSetup of the worksheet
const pageSetup = workbook.getWorksheets().get(0).getPageSetup();

// Setting the printing order of the pages to over then down
pageSetup.setOrder(AsposeCells.PrintOrderType.OverThenDown);

// Save the workbook.
workbook.save(path.join(dataDir, "SetPageOrder_out.xls"));
