If you’re not printing on 8 1/2 x 11 paper, you have to let your printer know.
When printing custom invitation sizes, the step of communicating the particular paper size to the printer is often overlooked, resulting in incorrect printing.
By default, your printer assumes 8 1/2 x 11 size paper is in its tray. You must communicate otherwise for your non-standard size paper to print correctly. Where does this communication take place? Its located in the print driver that is automatically installed when you installed your printer. The print driver can be accessed just before you send the document to print.
Below, you will find step by step instructions on exactly how to access your print driver and input custom paper dimensions. Please be aware it is not enough to simply choose from one of the pre-defined paper sizes in the printer driver. Often, the paper size you’re printing is not shown among the common paper sizes and unless custom paper dimensions are entered, the printing will not be correct.
In rare cases, you will not be able to enter a custom size–a limitation of the particular printer and the print driver. In this case, consult with your printer’s manufacturer.
