Double-Byte and Multi-Byte Code Page Description Files
In ASCII mode the Epic 880TM Printer supports double byte code pages. Currently there are 4
Double Byte code pages available are: Code page 932, 936, 949 and 950
These code pages require an appropriate Unicode font be loaded that support all the characters in the requested code page.
Due to the large number of characters in these code pages. These files are not supported in a customer definable ASCII form like the Code page descriptions files described above. They are compiled and compressed into a 2 or 3 file code description set. One file is like the Code page description file in that it may be referenced just like the normal code page description files. The other two files are double byte and
Code Page Selection
In ASCII mode the Epic 880TM Printer supports many different international character sets. In IBM and EPOS printers, there are two ways of selecting a character set.
One way substitute’s international characters in the upper 128 characters of a standard character set. The substitution technique supports a few different countries. However, as more and more countries were added, too many characters were being replaced, and it became a problem for the application to match the characters displayed and printed.
To solve this problem, a second method of selecting a character set was developed – code pages. The printer and display use the same code page, and the application displays and prints the same characters. IBM and EPOS defined new commands to select code pages, and left the old commands in effect.
The Epic 880TM Printer supports international character sets as well as code pages. To allow the most flexibility for the application programmer, both methods are extended in the Epic 880TM Printer. In IBM mode, there are 19 character sets and 60 code pages. In EPOS mode, there are 57 character sets and five code pages.5
The Epic 880TM Printer allows the IBM code page selection command to choose character sets as well as normal IBM code pages. The EPOS character set select command has been extended to allow additional character sets over and above the 11 defined by EPOS. The EPOS code page select command has not been extended because there is no EPOS definition beyond the first six ID’s.
All characters in code pages as well as character sets are addressed as zero through
255.(Characters below 32 must be addressed with the [ESC] ^ <n> command.) Code pages may be changed at any time and are active for all features including rotated
5Epson provides limited code page support through ID to code page translation. Only six translations are defined.
