Either one of these methods returns the printer to what are called its defaults, which are the standard settings in effect every time you turn the printer on. Resetting the printer has two main effects. It returns the printing to single-strike pica, thus cancelling any other pitches or enhancements you may have turned on, and the current position of the print head becomes the top-of-page setting. The reset code does not cancel the draft mode if it has been selected with the panel button, but turning off the printer does cancel the draft setting. Some of the demonstration programs end with a reset code (Escape "@") so that the commands from one program will not interfere with the commands in the next one. After you run a program with a reset code in it, remember to change the top-of-page setting before you begin printing full pages. Disabling a program's reset code Some word processors and other applications programs send a reset code or initialization signal to the printer before sending data to be printed. Basically, the purpose of this code or signal is to cancel any settings that might interfere with the program's print control options. In most instances, this is fine. However, if you decide you want to set up the LQ to do something your applications program won't do, you have to make sure a reset code doesn't wipe out your new settings. Some initialization codes can be removed by using the setup or installation procedures that are part of many applications programs. Once you're into the setup procedure, find the section that deals with initialization, and see if the program has a list of codes it sends to the printer. If it does, the setup procedure usually allows you to cancel or remove the initialization settings. If the initialization code cannot be disabled or removed from your applications program,. you can usually use the program's print options function to control formatting and typestyles. Look in the manual for the program to find out how to select print options. 5-7

Either one of these methods returns the printer to what are called its

defaults, which are the standard settings in effect every time you turn

the printer on. Resetting the printer has two main effects. It returns the

printing to single-strike pica, thus cancelling any other pitches or

enhancements you may have turned on, and the current position of

the print head becomes the top-of-page setting. The reset code does

not cancel the draft mode if it has been selected with the panel button,

but turning off the printer does cancel the draft setting.

Some of the demonstration programs end with a reset code

(Escape “@”) so that the commands from one program will not inter-

fere with the commands in the next one. After you run a program with

a reset code in it, remember to change the top-of-page setting before

you begin printing full pages.

Disabling a program’s reset code

Some word processors and other applications programs send a reset

code or initialization signal to the printer before sending data to be

printed. Basically, the purpose of this code or signal is to cancel any

settings that might interfere with the program’s print control options.

In most instances, this is fine. However, if you decide you want to

set up the LQ to do something your applications program won’t do,

you have to make sure a reset code doesn’t wipe out your new set-

tings.

Some initialization codes can be removed by using the setup or

installation procedures that are part of many applications programs.

Once you’re into the setup procedure, find the section that deals with

initialization, and see if the program has a list of codes it sends to the

printer. If it does, the setup procedure usually allows you to cancel or

remove the initialization settings.

If the initialization code cannot be disabled or removed from your

applications program,. you can usually use the program’s print options

function to control formatting and typestyles. Look in the manual for

the program to find out how to select print options.
