How universal graphics is done
The printer extends all the emulations to support two additional escape sequences and
adds limited IPCL support.
IPCL (Ithaca Printer Control Language) is an ASCII method of sending printer
commands to the printer. In Ithaca PcOS emulation, IPCL command support is
extensive. In other emulations, IPCL support is limited to the following commands.
&%CR
Insert a [CR]
&%LF Insert a [LF]
&%UAxxx Feed xxx paper steps and cycle auto-cutter
&%CLx Select Color where x = 0 for the Left Pen or 1,2,3 for Right Pen
&%UBName& Begin defining universal graphic "Name"
&%UGName& End the definition of "Name"
&%URName& Run (print) universal graphic "Name"
&%UDName& Remove universal graphic "Name" from nonvolatile memory
&%USName& Flag universal graphic "Name" to be run when the printer is
turned on
&%UFALL& Erase all stored universal graphics. (Erases all User Store)
&%UQ& Prints a directory of the universal graphics currently stored in the
printer
&%UTx Changes the Name termination character from "&" to "x". "x" may
range from 21H to 255H
Note: The & used to flag the end of the Name string is not valid in PcOS
Ithaca emulation mode. You should use <0> or define the terminator with
the &%UTx command.
The extended Escape sequences are [ESC][US]… and [ESC][FS]…
The [ESC][US] commands are the same as the PcOS emulation. The [ESC][FS]
commands are not intended to be used by the customer. They provide the universal
graphics support. Because graphics would be very difficult to generate and are not
supported by any graphics drives other than PJColor .
How to use IPCL commands in text strings
If your software allows you to pass text strings to the printer, you should be able to use
the universal graphics commands. Most POS software allows user customization of the
text message printed at the beginning and the end of the receipt.
To use the Universal IPCL commands simply place them in a text string like the following
example; note that your results may vary depending on the operation system, software
and the ability to pass ASCII Characters.
Load and store named graphic image

First you must create the graphic image using the PJColor Color Image
Converter and save the image to a file. See the section
