LQ and FX Emulation Command Summary SI / ESC SI These commands print 10 cpi characters in a 16.66 cpi font, and 12 cpi characters in a 20 cpi font. On an actual LQ or FX printer, these commands condense the font. ESC x This command is normally used to select between draft and LQ quality with an LQ or FX printer. However, this command has no effect on your printer's print quality since all characters are printed at 300 dpi (dots per inch). ESC w This command produces double-height characters but differs between LQ and FX emulation 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 weight. 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. Appendix C C-17
