OnPay supports all major browsers, but please make sure that you have an updated version of whichever browser that you may be using. Some features of OnPay will not be available on older versions of certain browsers. Please keep in mind that Microsoft is no longer updating Internet Explorer since they have introduced Edge.
Please also be aware that some browsers have their own built in PDF viewers. Sometimes these will not bring up the same options that Adobe Reader will when you go to print checks. So, you will not be able to change the scaling options, meaning if you try to print the checks they will not line up properly. If this happens, you can download the checks and then open them in Adobe Reader.
