Every user is able to configure print and page setup inside the browser he is using.
In the example below we used a Mozilla browser.
In general the same settings are found at the same location in other browsers.
If your not comfortable with your browser, try to use another browser or ask the distributing browser company for advice.
1. Open "File".
2. Select "Print Preview".
3. The Print Preview-window opens. Check if you like the current print result.
4. If you do not like the result, select "Page Setup".
5. The Page Setup-window opens. Modify your settings into a better format (check margins, footer, header, orientation, background, etc).
6. Do not forget to click "OK", otherwise your modifications will not have been carried out.
Maybe you have to make a couple of modifications before you reach a good result. If your customer is using this sticker print function as well it could be usefull to tell him your print-settings.
