Report Format
The integral printer normally operates in continuous
forms mode without regard for page boundaries. You can,
however, enable report format in which printed output is
treated as a series of 66-line pages (a 3-line top margin, 60
lines of text, and a 3-line bottom margin). The margins and
text area together form an 8 112" X 11" page. The printer
uses a small tic mark to demarcate the end of one page and
the beginning of the next. Report format is illustrated in
figure 6-2.
From the keyboard, you enable and disable report format
using the
"REPORT PR I NT"
key ( . . ). This key alternately
enables and disables report format. When enabled, an as-
terisk appears in the key label.
From a program executing. in a host computer, you enable
and disable report format using the following escape se-
quences:
ENABLE:
<ESC>&p17C
DISABLE:
<ESC>&p19C
Once enabled, report format remains enabled until ex-
plicitly disabled, until metric format is enabled, until a
hard reset is performed, or until the power is turned off.
Metric Format
The integral printer normally operates in continuous
forms mode without regard for page boundaries. You can,
however, enable metric format in which printed output is
treated as a series of 70-line pages (a 3-line top margin, 64
lines of text, and a 3-line bottom margin). The printer uses
a small tic mark to demarcate the end of one page and the
beginning of the next. Metric format is illustrated in figure
6-2.
From the keyboard, you enable and disable metric format
using the
"METR
I
CPR
I
NT"
key
(m).
This key alternately
enables and disables metric format. When enabled, an
asterisk appears in the key label.
From a program executing in a host computer, you enable
and disable metric format using the following escape se-
quences:
ENABLE:
<ESC>&p18C
DISABLE:
<ESC>&p19C
Once enabled, metric format remains enabled until ex-
plicitly disabled, until report format is enabled, until a
hard reset is performed, or until the power is turned off.

Data Logging
The HP 2624A includes a mechanism called "data logging"
whereby data can be automatically routed to the integral
printer and/or an external printer. There are two types of
data logging: top and bottom.
TOP LOGGING. When display memory is filled and an-
other line of data is entered through the keyboard or
received over a data comm line, the top line in display
memory is purged to make room for the new line. With top
logging, each line that is purged from the top of display
memory is printed. Thus, while the line is "lost" from
display memory, it is maintained in hard copy form.
BOTTOM LOGGING. With bottom logging, each time
the cursor moves from one line to another as the result of an
explicit line feed or an end-of-line-wraparound, the line
from which the cursor moved is printed. This feature al-
lows you to maintain a hard copy "trail" of all lines added to
display memory in the order in which they were entered
and/or received.
