Epson EPL-7000 User Manual - Page 304

LQ and FX Emulation Modes ESC w This command produces double-height characters but differs between LQ and FX 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 series printers print only the bottom half of the characters. The EPL-7000 printer prints the entire character. FX mode - When combining ESC w and ESC W to produce double-width, double-height characters, FX series printers do not increase the stroke weight for vertical lines. The EPL-7000 printer in FX emulation does increase the vertical line weight. Also, when this command is sent with the print position set at the first line of the page, the FX changes the baseline position in order to print the entire character. For the EPL-7000, the baseline is not changed. ESC &, ESC K, ESC L, ESC Y, ESC Z, ESC *, and ESC ˆ 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 Epson FX or LQ printer. ESC C, ESC CO When you send the ESC C or ESC CO command to change the page length on LQ or FX printers, you can print more than one page on the same sheet of paper. Because the EPL-7000 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 CO command differs from the actual page length. Appendix C C-13
