Plus, some printers will auto-detect the paper width.
The biggest detail is that when you print, be sure and select a print size and print orientation that fits the paper. Over time, many printer operators develop print size layouts intended for a variety of paper sizes. With my printer, for instance, I have layouts intended for 16” 24” and 44” paper widths. If I select a paper width that’s larger than the actual paper installed, that can make for a problem.
Also, you can waste a lot of paper if you print something landscape when portrait would more closley fit the installed paper width. If the print job offers a print preview option, this is very helpful to make sure you are getting the best use of the paper.
