INTRODUCTION
The HP 2624A Display Station includes an asynchronous
RS-232C port for connecting the terminal to an external
printer. As an option, your terminal may also include an
integral printer.
With either or both printers present, you may do any of the
following:
• Print the line containing the cursor.
• Print all lines from the one containing the cursor
through the bottom line on the screen.
• Print all lines from the one containing the cursor
through the end of display memory.
• Copy a configuration menu from the screen to either or
both printers.
• Enable data logging (to occur either from the top or
bottom of display memory, as designated by you when
you enable it).
• Perform a line feed (advance the paper one line).
• Perform a form feed.
With the optional integral printer, you may also do any of
the following:
• Select expanded, compressed, or normal-sized print
characters.
• Select continuous forms mode, report format (60 text
lines per page), or metric format (64 text lines per page).
All of the above printer control functions can be initiated
either locally by operator keystrokes or remotely by escape
sequences sent from a host computer.

DATA TRANSFERS
If you define the integral and/or an external printer as
destination ("to") devices, you can use the
"device
con t r

I"
set of system function keys to print one or more
lines of data from display memory. One way of getting to
the
"device cont rol"
keys is the following keystroke
sequence:

This changes the function key labels to the following:

For device-to-device data transfers initiated through the
keyboard, display memory is always the source ("from")
device while the integral printer and/or an external print-
er are the destination ("to") devices. To select an external
printer as the "to" device, press the
"TO EXT DEV"
function
key
(m).
To select the integral printer as the "to" device,
press the
"TO
I
NT PRT"
function key
em).
When a printer
is selected as the current "to" device, an asterisk appears in
the associated function key label. You may, if you so desire,
have both printers selected as "to" devices simultaneously.
Copy Line
When either or both ofthe printers is selected as a destina-
tion ("to") device, you can copy the line containing the
cursor from the display screen to the printer(s). Block ter-
minators and non-displaying terminators are ignored.
After the line is printed, the cursor moves to the leftmost
column in the next lower line (column 0, NOT the left
margin).
From the keyboard, you copy one line of data using the
"COPY LINE"
key
( m )
in the
"device control"
set of
system function keys.
From a program executing in a host computer, you copy one
line of data using the following escape sequence:
<ESC>&pB
or
<ESC>&pOB
Copy Page
When either or both of the printers is selected as a destina-
tion ("to") device, you can copy all lines from the one
containing the cursor through the last one visible on the
display screen to the printer(s). Block terminators and
non-displaying terminators are ignored. After each line is
printed, the cursor moves to the leftmost column in the
next lower line (column 0, NOT the left margin).
