Setting Up Your Printer
Allegro2 19
If your Printer is controlled by a third-party software package,
please refer to the operator’s manual supplied with the software
package for operating instructions. For detailed explanations of the
Printer’s commands and label format structure, refer to the
Programmer's Manual.
A typical application for a PC-based system is printing labels for
manufacturing production in a Batch Mode. In these applications, a
data-base of part numbers, descriptions, warehouse locations, and
shipping weight information may be obtained through the PC.
Through an entry screen, the operator selects the type and quantity
of labels to be printed. The PC sends the data serially to the Printer
and the operator receives the labels requested.
Connecting to Your Minicomputer
Connecting the Printer to most minicomputers is similar to
connecting to a PC. Most minicomputers made by Digital
Equipment, Hewlett Packard, Unisys, etc., have ASCII RS-232C
serial ports similar to PCs. Interfacing to IBM systems sometimes
requires a protocol converter. The cable you select for connecting
the Printer to a minicomputer will vary depending on the type of
computer system you have. Diagrams in Appendix D describe a
straight serial cable and a null modem cable, one of these two cables
should work on your system.
Connecting to Your Non-ASCII Device
The Printer uses the standard ASCII for conversion of byte patterns
to characters. The standard port for receiving data expects
asynchronous ASCII serial data. If your host system uses an
interface other than ASCII character-based RS-232C, you will need
an interface converter.
Some hosts, such as IBM mainframe equipment, do not use the
ASCII standard for data encoding, rather many IBM machines use
EBCDIC.
