22 Page Device Parameters
Table 2-2 Page device parameters
Key Type Default Description
BeginPage
procedure
{pop}
This procedure is executed at the beginning of
each page. A BeginPage procedure occurs at
the end of setpagedevice, at the end of
showpage or copypage, and during any opera-
tion that reinstates a page device different from
the existing one.
EndPage
procedure
{exch
pop 2 ne}
This procedure is executed at the end of each
page. An EndPage procedure occurs at the
beginning of each showpage or copypage, and
when the current page device is about to be
replaced by a different page device.
ExitJamRecovery
boolean
false
If the value of this parameter is true, pages
that jam in the exit path are reprinted. If the
value of this parameter is false (jam recovery
disabled), pages that jam are not reprinted. In
this case, performance may be improved
because it is possible to overlap more page
processing. Value persists across power cycles.
FaxOptions
dictionary This dictionary contains parameters that direct
fax transmissions from a PostScript language
program. Refer to “Fax Parameters” on page 29
for further information about FaxOptions
defaults and the keys found in this dictionary.
HWResolution
array
[600 600]
This parameter controls the resolution of
the output.
ImagingBBox
array or
null
null
This parameter is an optional bounding box. If
not null, the value is an array of four numbers
in the default user coordinate system stating
lower-left x, lower-left y, upper-right x, and
upper-right y of the page image bounding box.
When a PostScript program specifies an
ImagingBBox, it asserts that it will not paint
any marks outside the rectangle. However, any
marks that fall outside the rectangle may still
be painted
