class PrintUserParams : SystemIDisposable
```

**Namespace:** `Datalogics::PDFL`

**Inherits from:** `SystemIDisposable`

## Description

A structure used to set parameters for print jobs.

Two structures provide settings for setting parameters for print jobs, PrintUserParams and PrintParams. PrintUserParams was created first, and then PrintParams was created as an extension of PrintUserParams, to provide more settings to account for changing technology.

When the system seeks to print a document it will pass the content and the print parameters, such as the page size, paper tray, and landscape v. portrait, to the print API in APDFL. If the setting is in PrintParams it will pass the document and parameters to PrintParams and then to PrintUserParams and from there to the print API to complete the printing process.

The print logic may take different code paths depending on whether or not the print content is being sent to a printer or to a file, or if the printing uses PostScript or not. When you see a print setting that appears in both PrintUserParams and PrintParams, such as "ShrinktoFit," set the appropriate value in both of these classes. Also, PrintParams offers a variety of settings related to PostScript, but the use of PrintParams is not limited to PostScript.

## Methods

### ChoosePaperSourceBySize

```csharp
void Datalogics.PDFL.PrintUserParams.ChoosePaperSourceBySize(double width, double height)
```

**Parameters**

- `width` (`double`): the desired width of the output in user units
- `height` (`double`): the desired height of the output in user units

**Returns:** `void`

Choose the best paper source for a given width and height.

Searches the printer's paper list for the smallest paper size that is greater than or equal to the given width and height, including with rotation, and sets up the job to print with that paper size.

To obtain width and height, specify the Right - Left and Top - Bottom of the MediaBox of a representative Page.

The printerName and portName must be set.

If you use this call in conjunction with PosePrintDialog, UseDefaultPrinter, or UpdateFromPrinterSettings, call this function after those functions.

Setting RotateAndCenter to True is recommended with this function.

### Dispose

```csharp
void Datalogics.PDFL.PrintUserParams.Dispose()
```

**Returns:** `void`

### EnumeratePaperSources

```csharp
System.Collections.Generic.IList< System.String > Datalogics.PDFL.PrintUserParams.EnumeratePaperSources()
```

**Returns:** `System.Collections.Generic.IList< System.String >`

Set of the tray/bin names.

Enumerates available tray/bin names for the specified printer.

### PaperSourceIdByName

```csharp
int Datalogics.PDFL.PrintUserParams.PaperSourceIdByName(string trayName)
```

**Parameters**

- `trayName` (`string`): the tray/bin's name whose number need to obtain.

**Returns:** `int`

Tray/Bin number corresponding to the specified name.

Obtain tray/bin number by its name.

**Returns:** `bool`

true if the user accepted the dialog box, false if it was cancelled

Set the print parameters by posing a dialog box to the user. The parameters set include the printer, page range, paper size, number of copies, and duplexing mode.

Changes to these parameters made by the user will be copied into the corresponding PrintUserParams fields. If you want to override the user's choices, change these fields after calling PosePrintDialog().

### UpdateFromPrinterSettings

```csharp
void Datalogics.PDFL.PrintUserParams.UpdateFromPrinterSettings(System.Drawing.Printing.PrinterSettings settings)
```

**Parameters**

- `settings` (`System.Drawing.Printing.PrinterSettings`): Printer settings
