HP 510 - Manual (Page 145)

Rotating an image
These topics detail all aspects of job rotation:
• Job rotation (HP-GL/2)
• Page size and rotation
• What is rotated?
Job rotation (HP-GL/2)
If the software in the driver does not specify the rotation setting, it can be specified in the front panel
(Paper > Page Format > Rotate).
Page size and rotation
Note that, when you rotate a job, the page size is enlarged to avoid clipping, because the trailing and leading
margins are not the same size as the side margins.
