Transparent Print
The transparent print feature enables users to attach a printer to the
auxiliary port available on most video display terminals. Data can
then be directed from the host through the terminal to the printer,
without disturbing the normal keyboard entry and display functions.
This enables you to attach a terminal and a printer to the same port.
Follow these basic steps to set up transparent print:
1. Attach a printer to the auxiliary port on the terminal.
2. Edit the /comtrol/rckt/tprint.cfg file to configure the tprint port.
3. Run /comtrol/rckt/psetup to inform the driver of the new
configuration.
4. Enable the terminal for logins.
5. Direct output to the tprint port name.
For more information, see the related discussions that follow.
TPRINT.CFG
Each printer device must be described in the tprint.cfg file. This
description consists of a set of statements describing the terminal and
printer used. Each statement consists of a keyword/parameter pair, in
the form, keyword=parameter.
See your hardware owner’s manuals for information regarding the
statements required by your printer and operating system.
The tprint.cfg configuration statements consist of up to five lines for
each transparent port used:
device=
auxon=
auxoff=
printcps=
option=
For example, the following configuration can be found in the /comtrol/
rckt/tprint.sample file:
# device tpr0a (attached to device ttyr0a
# terminal: Link Technologies model 220
# printer: Okidata model u92
device=tpr0a
auxon=(esc [ 5 i)
auxoff=(esc [ 4 i)
printcps=90
option=onclr
The keywords are described further in the following table.
