ESC w
This command produces double-height characters but differs between LQ and FX emu -
lation modes, as follows:
❐ LQ mode - If you send the ESC w command when the print position is set at the first
line of the logical page, LQ printers print only the bottom half of the characters. Your
printer prints the entire character.
❐ FX mode - When combining ESC w and ESC W to produce double-width, double-
height characters, FX printers do not increase the stroke weight for vertical lines.
Your printer in FX emulation does increase the vertical line width. Also, when this
command is set with the print position set at the first line of the page, FX printers
change the baseline position in order to print the entire character. For your printer,
the baseline is not changed.
ESC &, ESC K, ESC L, ESC Y, ESC Z, ESC *, and ESC ^
This printer uses an image processing technique that emulates, as closely as possible,
the image densities available on FX and LQ printers. Because of this process, the
graphics commands listed above do not produce exactly the same output on the
printer that they would on an FX or LQ printer.
ESC C, ESC C0 (zero)
When you send the ESC C or ESC C0 command to change the page length on the LQ
or FX printers, you can print more than one page on the same sheet of paper. Because
your printer processes data page-by-page, each page must be printed on a separate
sheet of paper, so exact LQ or FX emulation cannot be provided. Problems will occur
when the page length set with the ESC C or ESC C0 command differs from the actual
page length.
DEL
The printer handles the DEL command as a BS command. Print position return is the
same as for an FX or LQ printer, although your printer does not clear previous charac -
ters.
CAN
FX and LQ printers clear the data in their print buffer with this command; your printer
prints the data.
ESC EM
Your printer supports 1, 2, and R for n.
