Properties
Collation
CoreWebView2PrintCollation Collation
Printer collation. See CoreWebView2PrintCollation for descriptions of collation. The default value is CoreWebView2PrintCollation.Default.
Printing uses default value of printer's collation if an invalid value is provided for the specific printer.

Orientation
CoreWebView2PrintOrientation Orientation
The orientation can be portrait or landscape. The default orientation is portrait. See CoreWebView2PrintOrientation.
PageHeight
double PageHeight
The page height in inches. The default height is 11 inches. If the provided page height is less than or equal to zero, the current value is not changed and an ArgumentException is thrown.
PageRanges
string PageRanges
Page range to print. Defaults to empty string, which means print all pages.
The PageRanges property is a list of page ranges specifying one or more pages that
should be printed separated by commas. Any whitespace between page ranges is ignored.
A valid page range is either a single integer identifying the page to print, or a range
in the form [start page]-[last page] where start page and last page are integers
identifying the first and last inclusive pages respectively to print.
Every page identifier is an integer greater than 0 unless wildcards are used (see below examples).
The first page is 1.
In a page range of the form [start page]-[last page] the start page number must be
larger than 0 and less than or equal to the document's total page count.
If the start page is not present, then 1 is used as the start page.
The last page must be larger than the start page.
If the last page is not present, then the document total page count is used as the last page.
Repeating a page does not print it multiple times. To print multiple times, use the Copies property.
The pages are always printed in ascending order, even if specified in non-ascending order."
If page range is not valid or if a page is greater than document total page count, ArgumentException is thrown.
The following examples assume a document with 20 total pages.
| Example | Result | Notes |
|---|---|---|
| "2" | Page 2 | |
| "1-4, 9, 3-6, 10, 11" | Pages 1-6, 9-11 | |
| "1-4, -6" | Pages 1-6 | The "-6" is interpreted as "1-6". |
| "2-" | Pages 2-20 | The "2-" is interpreted as "pages 2 to the end of the document". |
| "4-2, 11, -6" | Invalid | "4-2" is an invalid range. |
| "-" | Pages 1-20 | The "-" is interpreted as "page 1 to the end of the document". |
| "1-4dsf, 11" | Invalid | |
| "2-2" | Page 2 |
