DBCS Mode
When the printer is in DBCS mode, it can print double byte characters—
characters that require two bytes to define. It can also print a limited number
of single byte ASCII characters. If a form hex 0x20 through hex 0x7F is sent to
the printer, it will be printed as a standard ASCII character. If a character is
larger that 0x7F, it will be combined with the next character to produce one
DBCS character.
DBCS characters are only available in the LQ, Near LQ, Normal, Hi-Speed,
Super Hi-Speed, and Ultra Hi-Speed typefaces. The command to select
DBCS mode (FS &) switches the printer to one of these typefaces. Near LQ is
the default typeface, but if another print quality has been selected previously
through the FS x command, then that print quality is the DBCS typeface
selected.
The character printed when the printer combines two characters into one
double byte character depends on the character set of your particular printer.
Configuring The LQ-1600K Emulation With Control Codes
The remainder of this chapter describes the LQ-1600K printer control
language codes that may be sent from a host computer attached to the printer
in order to invoke and configure numerous LQ-1600K emulation functions.
Format For Control Code Descriptions
The following information is listed for each code (where applicable and
possible) in this chapter:
ASCII Mnemonic. The ASCII name for the control code.
Hex Code. The hexadecimal equivalent of the code. (For octal equivalents,
refer to Appendix A.)
Dec Code. The decimal equivalent of the code.
Purpose. The function(s) of the control code.
Expression. The control codes used in the BASIC programming language.
Comment. A description of exceptions or limitations to normal use.
Example. A sample expression written in the BASIC programming language
is provided for some control codes to illustrate how the code is used.
