I have been experementing with printing invoices using Javascript and Tailwindcss. After several trials and errors the following is the best configuration I found to get the optimal results.
(optional) Configure Tailwindcss
If you are using tailwindcss to style your invoice then you can set the following configuration to access to 'print' and 'screen' prefixes that you can use to hide/show content based on your requirements.
CODE
/** @type {import('tailwindcss').Config} */
export default {
content: ['./src/**/*.{html,js,svelte,ts}'],
theme: {
extend: {
screens: {
print: { raw: 'print' },
screen: { raw: 'screen' }
},
// ...
}
},
plugins: []
};
Now you can utilize this as follows:
CODE
<div class="screen:bg-red-300 print:bg-white" />
Add this to your primary CSS file
CODE
/* This will hide the extra header and footer contents added by the browser. */
@media print {
@page {
margin: 0.3in 0.7in 0.3in 0.7in !important;
}
}
/* Change this as you like */
@media screen {
html,
body {
width: 100vw;
height: 100vh;
display: flex;
overflow: auto;
background-color: #982b44;
}
}
Always use a separate route, do not use a pop up window.
Also, set the document title for better experience.
CODE
<head>
...
<title>your-file-name</title>
...
</head>
or
CODE
document.title = "your-file-name"
Use join('') to hide the unnecessary commas, if you are looping through the items like below.
CODE
const tableRows = orders.map((item, index) => {
// ...
return `
<tr class="border-b border-gray-200 break-inside-avoid break-before-auto">
<td class="max-w-0 py-2 pl-4 pr-3 text-sm sm:pl-0">
<div class="font-medium text-gray-900"><span class="mr-4 text-gray-500">${index + 1}.</span>${item.name}</div>
</td>
<td class="hidden px-3 py-2 text-right text-sm text-gray-500 sm:table-cell">${quantity}${weightUnit}</td>
<td class="hidden px-3 py-2 text-right text-sm text-gray-500 sm:table-cell">${price}</td>
<td class="py-2 pl-3 pr-4 text-right text-sm text-gray-500 sm:pr-0"><span class="text-xs">${item.currency}</span> ${total}</td>
</tr>
`;
});
and display this as,
CODE
<tbody>
${tableRows.join('')}
</tbody>
Sample Receipt
CODE
export function receiptGenerator(seller: any, order: any): string {
const panNum = 'XXXXXXXX';
const companyLogo = // your-company-logo
const deliveryAddr = order.deliveryAddress;
let vat = 0.0;
let subTotal = 0;
let currency = '';
const tableRows = order.items.map((item, index) => {
// ...
return `
<tr class="border-b border-gray-200 break-inside-avoid break-before-auto">
