VueToPrint Component
Props
| Name | Type | Description |
|---|---|---|
bodyClass? | string | One or more class names to pass to the print window, separated by spaces |
content | function | A DOM element to print. |
copyStyles? | boolean | Copy all <style> and <link type="stylesheet" /> tags from <head> inside the parent window into the print window. (default: true) |
documentTitle? | string | Set the title for printing when saving as a file |
fonts? | { family: string, source: string; weight?: string; style?: string; }[] | You may optionally provide a list of fonts which will be loaded into the printing iframe. This is useful if you are using custom fonts |
onAfterPrint? | function | Callback function that triggers after the print dialog is closed regardless of if the user selected to print or cancel |
onBeforeGetContent? | function | Callback function that triggers before the library gathers the page's content. Either returns void or a Promise. This can be used to change the content on the page before printing |
onBeforePrint? | function | Callback function that triggers before print. Either returns void or a Promise. Note: this function is run immediately prior to printing, but after the page's content has been gathered. To modify content before printing, use onBeforeGetContent instead |
onPrintError? | function | Callback function (signature: function(errorLocation: 'onBeforePrint' | 'onBeforeGetContent' | 'print', error: Error)) that will be called if there is a printing error serious enough that printing cannot continue. Currently limited to Promise rejections in onBeforeGetContent, onBeforePrint, and print. Use this to attempt to print again. errorLocation will tell you in which callback the Promise was rejected |
pageStyle? | string or function | We set some basic styles to help improve page printing. Use this to override them and provide your own. If given as a function it must return a string |
print? | function | If passed, this function will be used instead of window.print to print the content. This function is passed the HTMLIFrameElement which is the iframe used internally to gather content for printing. When finished, this function must return a Promise. Use this to print in non-browser environments such as Electron |
removeAfterPrint? | boolean | Remove the print iframe after action. Defaults to false |
suppressErrors? | boolean | When passed, prevents console logging of errors |
nonce? | string | Set the nonce attribute for whitelisting script and style -elements for CSP (content security policy) |
Slots
| Name | Type | Description |
|---|---|---|
default | v-slot="{ handlePrint: () => void }" | A function that returns a Vue Node or Element. handlePrint is a function that triggers the print dialog. |
trigger? | v-slot:trigger | A function that returns a Vue Node or Element. Note: under the hood, we inject a custom onClick prop into the returned Component/Element. As such, do not provide an onClick prop to the root node returned by trigger, as it will be overwritten |
