Documents are printed in invalid size (for instance, in Letter instead of Legal).
The printer driver has incorrect length and width values for the desired paper size, e.g. 2794 x 2159 instead of 2159 x 3556 for Legal.
If those settings were done manually for some reason, please use some custom paper size instead of one of well-known formats.
If setting paper size manually was not performed, please consider updating the printer driver.
