  3.1. General description of the LP-50

The LP-50 is a thermal printer designed to print small sized labels and

graphics on thermo-sensitive paper. It is particularly useful when printing
information, arranged in a template form, which has to be partially modified
under customer demand.

The memory of the printer contains a command file which stores data

for the arrangement and design of the separate graphic elements, easing
your work considerably when you have to print a greater number of labels.
On the other hand it supports the PCX format and gives you the opportunity
to design the graphics of parts of the label with an appropriate program
under Windows and store it in the memory of the printer in advance. The
built-in 6 matrix fonts with different sizes, as well as the freely selectable
option  for  additional  scaling  and  rotation,  gives  you  greater  freedom  in
designing the inscriptions on your labels. If those fonts do not satisfy your
requirements  you  are  free  to  load  additional  fonts  in  the  memory  of  the
device.

The  device  may  be  used  to  print  information  from  Windows  (Word,

Notepad or other programs) after the installation of the necessary driver.

In  conclusion,  the  LP-50  offers  fast  and  flexible  printing  at  a  quality

which is very similar to that of most contemporary laser printers (printing
density - 203 dpi).

  3.2. Operating the printer

The  functions  of  the  printer  are  controlled  by  commands,  sent  via  a

serial interface. It is able to maintain 7 baud rates set up by adjusting the
configuration  keys:  2400,  4800,  9600,  19200,  38400,  57600  and  115200
bps,  8  bits,  no  parity  bit.  The  printer  uses  a  hardware  protocol,  which
permits its direct control under DOS but can also support Xon/Xoff protocol.

Each  printer  command  consists  of  one  line  of  text  ending  with  a  LF

(0Ah). Commands are made up of one or two letters followed by a different
number  of  parameters  divided  by  a  comma.  Intervals  MUST  NOT  BE
ENTERED in these commands – this will be treated as syntax error.
