Software Overview
purpose tray is selected in this way, or by using the
setpapertray
operator, it is
treated like the main cassette. Up to 50 sheets of paper may be stacked in it, and it feeds
continuously until it is empty, at which time the paper-out light comes on.
When a job requires a particular paper size, it invokes one of the paper tray selection
operators listed in Table 2-1 before it generates an image. That paper tray selection stays
in effect for the duration of the job. The server restores the default paper tray selection
when that job is finished. Table 1-7, in Chapter 1, defines the different paper sizes.
If there is more than one paper source with the size of paper requested, the PostScript
interpreter follows the
Priority
array from
InputAttributes
in the
setpagedevice
dictionary. The value of
Priority
is an array of integers. The first
integer in the array represents the media source with the highest priority. When a
setpagedevice
request matches two or more media sources,
setpagedevice
chooses the one with the highest priority in the array of integers. If none of the matching
sources appears in the array,
setpagedevice
chooses among them arbitrarily.
