For each of the variables and counters, defined in the form, send a single-line text ending
in (ASCII code 10). The variables are sent first, then the counters, by ascending
number. If you want to preserve the old value of a variable, send a blank line (only
).

Send print command Pn,m. m is the number of identical labels to be printed. n
defines how many sets of m labels will be printed. This can be used when we work with
counters – after printing a set of labels their value will change automatically. To print one
label, the value of n and m must be 1.

For more information read the An example of creating a label for digital scales and the
manual for the printer.

Question:

What is the largest size of a graphic the printer can load?

Answer:

The file size depends on the free memory space, but it cannot exceed 48

KB. The printers support only PCX monochrome format, but the program can load also
monochrome BMP graphics by converting them before sending them to the printer. Since
the PCX files are compressed, you may assume that the size, after conversion will
decrease (graphics that are a result from a photo, make an exception – usually they cannot
be compressed). If the graphic has X and Y values larger that the label’s, clip off the
unwanted parts or resize it beforehand not to occupy memory space unnecessarily.
Colour graphics can be converted to black-and-white images from Tools->Color to Black
& White Converter èëè or other application.

Question:

The barcode element on the label is not printed out

Answer:

You may have entered unalloyed barcode data. Usually this happens when

the barcode uses a variable – the change in the variable made the barcode invalid. Invalid
barcode will be displayed on the screen as crossed with a red line. Check the barcode
data. You can reference EAN 13, EAN 8, UPC-A, UPC-E, Code 128, EAN 128, Code
39, Code 93
and Interleaved 2 of 5.

Question:

Can I use DW-PRT24T to print from the standard Windows applications

(MS Word, Excel or Paint) and how?
Answer:

Yes. If you install a driver for a printer working with EPL2 language, you

can print from any Win application. There are drivers for Windows 2000 and Windows
XP in the installation diskette. For Windows 95 and Windows 98 you can download
drivers at http://www.zebra.com. The Zebra LP2742 comes closest to the label size and
settings for DW-PRT24T The DW-PRT24T Compatibility switch MUST be turned off.
