page-size settings have no effect on PostScript files
that already contain page-size information, which
includes all PostScript files sent using one of the
HP Designjet PostScript drivers supplied with this
printer.

If you are using the front-panel PS Scale

→

Fit to page

option, then the printer uses the page size set in the
printer's front-panel as follows:

If the page size is set to a discrete size, it uses the
specified page size.

If the page size is set to Software, the printer
calculates the page width as the width of the loaded
paper, and the page length as 1.5 times the width of
the loaded paper.

If the page size is set to Inked area, the printer
calculates the page width as the width of the loaded
paper and the page length as the height of the inked

area plus the top and bottom margins of
the page.

If the page size is set to a “Best…” option,
the printer calculates the page length as
1.5 times the page width.
