Model 810
Receive-Only
Printer

Copyright ©1978, Texas Instruments

Model
810
Receive-Only
Printer
The Model 810 Receive-Only
Printer
is
a multi-copy, impact
printer
utilizing a unique look-ahead feature
controlled by
an
on-board
micro-
processor to effect optimized bidirec-
tional printing.
Speed
of
the Model 810
is
150
cps
with
an
effective
throughput
from 60
full 132-character lines-per-minute,
up
to
440 lines-per-minute
maximum
with
an
average
of
10
character
lines.
Features
High Speed Printing
Maximum
throughput
is
achieved by
using a look-ahead technique. In-
creased efficiency
is
attained
because
the printhead need
not
return
to the
left margin for each new line.
Optimized bidirectional
pnntmg
minimizes printhead travel time
and
correspondingly increases available
print
time.

Reliabili~y
TI
microprocessor,
MOS/LSI
integrated circuits,
and
TI-built wire
matrix
printhead
are the keys to
performance
and
reliable, long-life
operation.
The
810's reliability
is
evident in
our
MTBF
figures:
print-
head
150

6 characters,
ribbon
5 to 7 x
10
6 characters,
and
the
810
MTBF
is 2000 hrs. (excluding
printhead, regardless
of
duty
cycle).
Multi-Copy Capability
The 1 x 7 wire matrix printhead built
by
TI
provides clear, legible printing
of
an original and up to 5 copies.
Off-Line Test
Allows
operator
to verify
printer
operation
without expensive test
equipment
or
training.

Interfacing the 810
The
Model
810 is available with
an
EIA
RS/232-C
Serial
Data
Interface
as
standard,
with
TTY
Current
Loop
and
Parallel Interfaces offered as
options.
Each
of
the interfaces also
has the
option
of
Line Buffering.
LBE
-Line buffering with
EIA
interface;
LBP
-Line buffering with
parallel interface;
and
LBT
-Line buffering with
TTY
interface.
(See Table 4 for interface specifica-
tions for all interfaces.)
The
standard
interfaces,
without
line
buffering, go busy when
the
rate
of
the incoming
data
exceeds the
print
speed
and
causes the buffer
to
be
filled. This may
happen
at
any
place
along
the
data
stream, thereby
re··
quiring
busy status
to
be
monitored
after
each character. (See timing
diagrams, Figures 5
and
7.)
With
Line Buffering, receipt
of
the
132nd printable
character
causes the
printer
to
go busy until either
the
buffer is cleared
or
printing
begins.
In
addition,
CR,
LF,
FF,
VT, Delete,
and
DC3
characters will also cause
busy
conditions.
This
enables the
transmitting
device
to
only
look
at
busy
status
following the
trans-
mission
of
a block
of
132 printable
characters
or
less, instead
of
after
each character. (See timing diagrams,
Figures 6
and
7.)
NOTE:
Transmitter
stops sending
data
when the 810 is busy
Line Buffering modifies the following
machine performances:
1.
Throughput
may be effectively
decreased
due
to always going busy
after
each 132 characters,
or
at
the
end
of
each line.
2.
The
software
programmable
option
of
variable line widths is
not
functional with Line Buffering.
The line width is fixed
at
132
characters.

The Model 810 Printer as a 990 Computer Peripheral
The 810 kit supplied by Texas
Instruments for the 990 Minicom-
puter,
Part
Number
938120-0001,
consists
of
the Mode1810 Line
Printer
with full
ASCII
character set
and
vertical forms control with com-
pressed print, a 9 meter (30-foot)
cable, interface module, papertakeup
tray
and
an
installation
and
operation
manual.
The Model 990
Computer
System
provides control
of
the line printer
and
sends
data
at
a 4800
baud
burst
rate via the interface module
to
the
line printerfor printing. Theinterface
is
a full-duplex, RS-232-C circuit,
half-size printed-circuit
board
that
installs in a communications register
unit
(CRU)
slot
of
the Model 990
Computer. The interface module
receives serial
data
and
commands
from the
computer
CRU,
converts
them
to EIA levels
and
sends them to
the line printer. The interface module
also receives status from the printer
and
routes these signals
to
the com-
puter.
The
half-size interface
board
may be installed in either side
of
a
Model 990
Computer
CR
U slot
or
in
a Model 990 110 expansion chassis
slot.
Versatility
of
locating the printer
remotely
is
provided via the optional
extension
cables
available
in
increments up
to
1000 feet (304.8 M.).
Operating in conjunction with the
appropriate
Model 990
Computer
Operating System software, the print-
er
provides reliable hard copy
of
high-
speed
data
output
from the computer.
Software
Support
To
operate a line printer, software
routines must provide initialization,
character transfer, and end-of-data
reporting. Standalone software pro-
grams for printer operation may be
easily designed
and
implemented;
however,
other
than
operational tests,
output
to
the printer
is
normally
accomplished by calling the device
service routine
of
the 990
Computer
DXI0
or
TX990 Operating System.
Service routines implemented
under
the operating systems use SBO, SBZ,
TB,
LDCR
and
STCR
instructions
of
the 990
Computer
instruction re-
pertoire.
Because the module
can
be inserted
into
any
of
the available
CR
U chassis
locations
wired
for
predefined
addresses, the base address becomes a
variable
that
depends
on
the module
chassis location.
Before selectinga chassis location, the
user must determine the address
that
the software handling routine expects
the module to recognize. Full details
for chassis locations
and
jumper
configurations are·provided in the 990
hardware reference manual.
The line printer diagnostics verify
proper
operation
of
the printer when
it
is
connected
to
a 990 Computer.
These diagnostics greatly simplify
maintenance
and
troubleshooting,
whether performed by trained,
experienced
Texas
Instruments
Service Engineers
or
by the user's
maintenance personnel. The diag-
nostics provided verify the perfor-
mance
of
the line printer as well as the
interconnecting cable, the interface
module
and
the
CRU
interface with
the
computer
system.
