LQ and FX Emulation Modes
ESC C, ESC C0
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 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 CO command
differs from the actual page length.
DEL
The printer handles the DEL command as a BS command. Print
portion return is the same as for an FX or LQ printer, although your
printer does not clear previous characters.
CAN
FX or 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.
