Should Every Web App That Supports Printing Include a Print Test Page?

I'm curious how other developers handle printing features in their applications.

If your app generates invoices, shipping labels, reports, tickets, or certificates, do you provide users with a way to verify their printer before they print important documents?

I've seen many support issues that turned out to be printer-related rather than application bugs. Problems like incorrect paper size, alignment issues, faded colors, poor print quality, or users selecting the wrong printer can all lead to failed print jobs.

Some operating systems include built-in printer test pages, but they're not always easy for users to find. Has anyone added a simple "Print Test Page" option directly into their application?

While looking into this topic, I came across a useful collection of printable test pages and printer troubleshooting resources.

I'm interested in hearing how others approach this.

• Do you provide your own print test page?

• Do you rely on the operating system's tools?

• Have printer-related issues generated a lot of support requests for your users?

• What has worked best in reducing printing problems?
