Integral Printer Control
All of the above printer operations can be initiated either locally, by operator keystrokes, or
~
remotely, by escape sequences sent from a program operating on a host computer. In b o t h '
cases, the integral printer must be selected as the destination device for device control
commands.
SELECTING THE INTEGRAL PRINTER AS THE "DESTINATION"
DEVICE
To control the printer, you must select it as the destination device for device control com-
mands. This can be done using either the function keys or an escape sequence. To do so using
the function keys, press the following keys, in sequence:
. , device control, "to"
devices, and TO INT PRT
An asterisk in the TO I NT PRT function key label indicates the internal printer is selected.
Alternate presses of the key display and delete the asterisk.
Programmatically, the CCto" devices are selected by including one or more CCd" parameters in
the device control escape sequence (more than one destination device can be selected). The
escape sequence to transfer data from the display to printer is of the form:
Ec&p <a>d <b>d <Y>
Where Ccy" lines of data are transferred from the display to devices CC
a "
and CCb". The values for
CCa " and CCb" may be 4 for the printer as specified in the Pr i nt er Code
4
entry on the Terminal
Configuration menu, or
6
for the integral printer. Use of the CCd" parameter alters the selec-
tion of the CCto devices" accordingly. If no CCd" parameter is specified, then the currently
assigned CCto" device(s) is used.
The Ccy" value can be either B (copy line), F (copy page), or M (copy all).
PAPER MOVEMENT
Two paper movement operations are allowed: line feed (advance line) and form feed (advance
page). However, a form feed can be produced only in Report or Metric modes. If a form feed is
attempted while not in Report or Metric modes, a line feed will be generated in place of the
form feed.
To perform one of these operations using the function keys, press the •
and
device control keys, in sequence. Then press either the ADVANCE LINE or ADVANCE PAGE
key, as desired. Pressing the ADVANCE LINE key causes the printer to advance the paper one
line. Pressing the ADVANCE PAGE key causes the printer to advance the paper to a new page, if
in Report or Metric mode, or to advance the paper one line, if not in Report or Metric mode.
Programmatically, you can produce a printer line feed by sending the following escape se-
quence:
Ec&p6d1P
C-2
