Epson 4100 manual Overlay Characters, OCR a OCR B

Operator's Guide 85

Overlay Characters

Pressing YES prints out the present settings:

•None (factory default)

•OCR A

•OCR B

•Accept User-Defined Characters

You can alter any active character set by overlaying one or more characters with either a predefined or a customized character map.

The printer contains two sets of predefined optical character recognition (OCR) maps. If you press YES to either OCR A or OCR B, the printer overlays some of the characters in the active characters set with these OCR characters. Your selection also becomes the default condition when you turn on the printer; for example, if you have selected the OCR A overlay and the NLQ* mode as defaults, then the active characters are OCR A characters when you turn on the printer. See Appendix D for OCR character maps.

If you press YES to "Accept User-Defined Characters," then downloaded characters presently in and/or subsequently downloaded to RAM using universal control commands can be mapped to the active character set. For the printer to accept downloaded customized characters, "Input Buffer Size" must be set to "Minimum" (Page 70). Unlike ROM-resident OCR characters, RAM-resident downloaded characters are lost when you turn off the printer.

*OCR characters are only allowed in Near Letter Quality (NLQ) mode. You cannot print OCR in draft quality mode.
