3. OUTER VIEW – CONTROL
3.1. General description of the DLP-50
The DLP–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 ar-
rangement 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 ad-
vance. 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 DLP–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). Com-
mands 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. Capital and small letters are identified. A detailed description
of the commands follows but it must be underlined that if a command starts with “;” it will
not generate any action on the part of the printer. This command may be used for
comments if we register the commands in a text file.
The fastest and easiest way to work with this printer is to use the accompanying
software program Label Editor (LpeditWH.exe) with the help of which you can ar-
range the elements of the label and see its final appearance on the computer screen even
before loading it into the printer. You can also print it out as a test trial. In order to work

Label Printer DLP-50

with the program successfully you will only need to have a general idea about the
functions of the printer. No special knowledge of the command language will be needed.
It is, of course, possible to prepare the information for printing in advance in a text file
and send this over the serial interface. Here is a description of one possible option for
preparing a label. It includes the following stages:
√√
√√
√ When working under DOS, the setup of the PC serial port is done with the MODE
COMn command in parallel to the setup of the printer, the format of this command being:
MODE COMn: BaudRate,n,8,1 where “n” is the number of the serial port and
“BaudRate” is the set up speed of the printer.
√√
√√
√ Select a name for the form. In any case it is advisable that the first line of the
text file should include the command for deleting a form of the same name (FK) - if
such exists, it will be deleted and replaced with the new one. You may then proceed
with the loading of a new form (command FS).
√√
√√
√ The length of the label is defined as well as the distance between the separate
labels. When using paper rolls these distances may be arbitrarily selected and set but
when working with self-adhesive labels, the length of the label must be set as close to its
actual dimensions as possible or the result may be incomplete printouts or empty labels.
The command Q, with all demanded parameters, is placed at the beginning of the text
file. Other commands may also be located here - starting point (R), select code table (I),
print density (D) and printing speed (S).
√√
√√
√ Designing the appearance of the label. Setting the elements, which will not be
subject to changes - they will need no counters or variables.
√√
√√
√ Setting and defining the elements subject to changes for each label. When some
of them are whole numbers and will change at regular rates a counter may be defined for
them. The rest must be variables. Depending on the case in question the information on
a given inscription or bar code may be set in several different variables and/or counters.
√ √
√ √
√ Defining variables and counters includes an assessment of their maximum pos-
sible length, alignment if and when the text is shorter than the maximum length, rate of
growth of the counters. The selection of the initiating text is important too if it is not
informative operating with the forms later on may be difficult. A line with the command
“V” or “C” is added in the text file for each counter or variable.
√√
√√
√ If we wish to insert graphics in the label, we must select a name and position for this
element and add a command for its layout in the text file (GG). The PCX file must be
prepared in advance on a PC and loaded into the printer prior to the execution of the
form. Before sending it to the printer its length must be verified and noted because the
loading command GM will demand this information. One possible way for doing this is by
sending the file from a terminal program with the DOS command COPY FileName
COMn: /B (sending the file as binary in this case is obligatory) - “n” is the number of the
serial port.
√√
√√
√ Selecting the position, font, size and orientation of the inscriptions on the label. “A”
commands are added for this purpose and if necessary, the inclusion of text modifiers

User’s Manual
17
for the counters and the variables for receiving the necessary strings for printing.
√√
√√
√ Selection of the type, position, size and orientation of the bar codes - if there will be
such - where modifiers may also have to be used.
√√
√√
√ If drawing of lines and frames is needed the following commands may be added
- LE, LO, LW, X.
√√
√√
√ At the end of the file the command FE is added - “Form End”.
√√
√√
√ The ready file is then sent to the printer: the form should be loaded into the memory
and be printed out in the list with the FI command.
With the FR command the form may become active. Values of the variables and
counters are added with the command “?” from a terminal program.
The forms, the graphics and loadable fonts use a common memory of the printer,
i.e., if we enter more graphic information there will be less memory left for forms and vice-
versa. This memory restriction comes for two reasons: on one hand not more than 512
forms, graphic files and fonts can be stored in the memory, irrespective of how small they
happen to be. On the other hand is the restriction related to the volume of the memory
itself, which is 244 kB. It must be remembered that the memory intended for storing
forms and graphics is distributed in parts of 256 bytes each meaning, that even a form of
only 10 bytes will take up 256 bytes of the volume of the memory.
The maximum length of the printed label is defined by the size of the graphic buffer
- 4000 dots (500 mm). The maximum width is 384 dots (48 mm) given complete width of
the paper roll - 58 mm.
When the printer is used for longer printing sessions the printing head unit may heat
considerably and printing is interrupted for cooling off. It is for this reason that when
printing labels with larger black areas the printer must be switched off at shorter interval
for cool off.
