activation or deactivation of those pages.
Every physical page is composed of one or more logical pages. When the
Hewlett-Packard 268x begins to print each physical page, it scans the
logical page table (LPT) for the first logical page labeled as ACTIVE. The
printer then continues searching the table sequentially for active pages
and printing them until it has printed the last active page. At this point,
the Hewlett-Packard 268x performs a physical page eject and starts the
sequence again. There must be at least one active LPT entry while the
Hewlett-Packard 268x is printing.
130/I16V Relative pen displacement:
parm1 A 16-bit signed integer containing the desired X-axis
displacement, in dots, of the pen from its current position.
parm2 A 16-bit signed integer containing the desired Y-axis
displacement, in dots, of the pen from its current position.
No pen movement results from requests to move the pen off the logical
page. Because the coordinate system is based upon the current logical
page itself and not upon the page's orientation with respect to the printer,
do not consider how the page has been rotated when assigning
displacement values to
parm1 and parm2 . Since the dot density for the
Hewlett-Packard 2680 (180 dots per inch) differs from the
Hewlett-Packard 2688 (300 dots per inch), the effects of
parm1 and parm2
are different.
131/I16V Absolute pen move:
parm1 An integer containing the X-coordinate, in dots, of the
point to move the pen.
parm2 An integer containing the Y-coordinate, in dots, of the
point to move the pen.
The values in
parm1 and parm2 are measured from the upper left corner of
the logical page. Do not take page rotation into account when assigning
coordinates as the printer does not move the pen if the location specified is
off the logical page. Since the dot density for the Hewlett-Packard 2680
(180 dots per inch) differs from the Hewlett-Packard 2688 (300 dots per
inch), the effects of
parm1 and parm2 are different.
132/I16V Define job characteristics:
parm1 (0:1) 0 = Ignored 1 = Printer does not print job separation
marks until next open job
parm1 (1:1) 0 = Ignored 1 = Parm2 contains maximum allowable
number of copies
parm2 Significant only if parm1 (1:1)=1 (Specifies the maximum
number of copies the printer makes, for any one page, for
the current job. The default maximum is 32,767.)
133/I16V Define physical page.
