Choosing a right place for the printer
TVS Proton has been designed to withstand rugged
environmental conditions. But to get the best performance from
your TVS Proton kindly take care of the following points:
Follow the guidelines given below carefully when selecting a
location for your printer .
Make sure you place your TVS Proton on a flat, clean
surface.
Do not forget that your printer will not function properly if it
is kept tilted or at an angle.
Always place the printer at connecting distance to the
network interface cable.
Leave sufficient free space around the printer for easy
operation and maintenance.
Avoid using or keeping the printer in places subject to rapid
changes in temperature and humidity. Keep it away from
direct sunlight, strong light, heat sources, excessive
moisture or dust.
Do not keep the printer near the places subject to shocks
and vibrations.
Make sure your electrical outlet is not controlled by wall
switches or automatic timers. Even a simple power
interruption can erase information in the memory of your
printer or computer.
Do not use the printer electrical outlet for operating large
motors or other appliances, as these can cause voltage
fluctuations.
Always keep the printer and computer system away from
loudspeakers or the base unit of cordless telephones, as

the mains power supply, unplug the power cord from the
electrical outlet.
2. Unplug the external power adaptor and interface cable from
the printer .
3. Remove paper/print media from the tractor.
For cleaning:
1. Open the Top cover and use a soft brush and carefully
brush away the dust from the carriage rail and the plate
below the Printhead (the front angle).
2. Clean the dust accumulated below the tractor using the
brush.
3. Clean the paper perforations accumulated on the paper
path using the brush.
4. Clean the outer case with soft, clean cloth.
Note
Do not use a hard or abrasive brush.
Do not use alcohol or thinner to clean the printer, since
these chemicals can damage the printer components as
well as the plastic casings.
Do not spill liquid/water on the printer mechanism or
electronic components.

Preserving the ribbon cassette
To ensure a long life for your cassette and optimum
performance from your TVS Proton,
1. Keep the new ribbon cassette in its packaging untill you

ASCII
American Standard Code for Information Interchange. A
standardized coding system for assigning numeral codes to
letters and symbols.
Bi-directional printing
Printing in which the print head prints in both directions
(bidirectionally), from left to right and then right to left. This
increases the print speed but may reduce precise vertical
alignment.
Buffer
The portion of the printer's memory used to store data before it
is printed.
Character table
A collection of letters, numbers, and symbols that provides you
with the set of characters used in a particular language.
Characters per inch (CPI)
The number of characters that can fit in one inch of a text line,
determined by the size of the chracters.
Continuous paper
Paper that has sprocket-feed holes on both long edges, is
perforated between pages, and is supplied in a folded stack.
Also called fanfold paper.
71
Page 78
Esc sequences
Special codes used to control printer functions, such as a
carriage return or line feed, instead of printing characters.
Default
Value settings or settings that take effect when a device (such
as a printer) is turned on, reset, or initialized. See also factory
settings.
Dot matrix
A method of printing in which each letter or symbol is formed
by a pattern (matrix) of individual dots.
Draft
The print modes used by your printer when you select Draft as
the font. The Draft font uses fewer dots per character for faster
printing. See also letter quality.
ESC/P
Abbreviation for PROTON standard code for printers, the
system of commands your computer uses to control your
printer. It is standard for all PROTON printers and supported
by most application software for personal computers.
ESC/P2
The enhanced version of the ESC/P printer command language.
Factory settings
The configuration settings for a computer or printer that are set
at the factory. If the device reverts to these settings when
initialized, they are called default settings, see also default.
72
Page 79
Fanfold paper
See continuous paper.
Font
A style of type designated by a name such as Roman or Sans
Serif.
Form feed (FF)
It advances the paper to the next top-of-form position.
Hex dump
A troubleshooting feature that helps identify the cause of

When the printer is in hex dump mode, it prints each code that
it receives in hexadecimal notation as well as in ASCII codes
that stand for characters. Also called data dump.
Interface
The connection (via a cable) between the computer and the
printer through which print data is transmitted to the printer.
Landscape
Printing that is oriented sideways on the page. This orientation
gives you a page that is wider than it is high and is useful for
printing spreadsheets. See also portrait.
Letter quality (LQ)
The print mode used by your printer, printing with letter quality
fonts provides better readability and appearance at a reduced
print speed. See also draft.
73
Page 80
Line feed (LF)
It advances the paper one line space.
Micro adjust
A printer feature that allows you to precisely adjust the tear-off
and top-of-form positions
Pitch
The size of the font, which is measured in the number of
character per inch (cpi). The standard is 10 cpi. See also
character per inch.
Platen
The black roller that provides a backing for the paper during
printing.
Portrait
Printing that is oriented upright on the page (as opposed to
landscape, in which printing is sideways on the page). This is
the standard orientation for printing letters or documents. See
also landscape.
Printable area
The area of a page on which the printer can print. It is smaller
than the physical size of the page because of margins.
Printer driver
A software program that sends commands for using the
functions of a particular printer.
74
Page 81
Reset
To return a printer to its default settings.
Resolution
