Using Configuration Parameters
A configuration parameter changes the way the 751G operates. Use either
of these methods to execute configuration parameters:
Scan EasySet bar code labels:
Use the EasySet application from Intermec Technologies Corporation to
print configuration labels. Scan labels to change imager configuration and
data transfer settings. See the EasySet online help for information.
Send Reader Commands through the Network or from an Application
See the Intermec Computer Command Reference Manual for information.
Configuring the Printer
The 751G works with a Zebra PT403 Portable Printer, which interfaces
through an I/O adapter (P/N 074143). Contact an Intermec representative
for information about this printer.
Methods for printing using Windows CE at this time is as follows:
• Add port drivers to print ASCII directly to the port.
• Use LinePrinter ActiveX Control from the Software Developer’s Kit
(SDK) - see the SDK User’s Manual for more information.
Directly to a Port
Printing directly to the port sends RAW data to the printer. The format of
this data depends upon your application and the printer capabilities.
You must understand the printer commands available for your specific
printer. Generally, applications just send raw ASCII text to the printer.
Since you are sending data to the printer from your application directly to
the port you are in complete control of the printers operations. This allows
you to do line printing (print one line at a time) rather than the page format
printing offered by the GDI approach. It is also much faster since data does
not have to be converted from one graphics format to the other (display to
printer). Most Intermec printers use Epson Escape Sequences to control
print format operations.
These commands are available in documentation you receive with your
printers or from technical support. Win32 APIs are required to print
directly to the port.
Directly to a Generic Serial Port
To print directly to a generic serial port printer (non–Intermec printers):
• Use CreateFile() to open ports - COM1: can be opened on most devices.
• Use WriteFile() to send data directly to the printer.
• Use CloseHandle() when you are finished printing to close the port.
