Operator's Guide 51

However, because printer drivers do not or cannot change some printer settings, such as the interface or emulation, those settings are important to the printer’s function. These settings must be correctly set as default settings so they are in effect when the printer is turned on.

If your printer’s configurations are set incorrectly for the interface, the printer driver in the software application cannot change that setting, and your documents will not be printed. If your printer emulation setting does not match the emulation setting in the software, your documents may not be printed or they may be printed incorrectly, with character substitutions and other problems.

If you must change configuration settings—and if those changes include interface and emulation changes— we advise that you change the interface and/or emulation settings first, before changing other settings. Also, consider the following guidelines:

•"Interface Option" changes (Page 63).

•If you select "Serial," do not forget to check the "Serial Options" settings (Page 64) for protocol, baud, number of data bits, parity, and the number of stop bits. These must agree with like settings on the computer.

•"Emulation" changes (Page 80).

•The selected emulation also affects the "Character Options" (Page 81).
