Star Micronics LC-500 Print direction command, CR centering at top of form, Strobe timing

Print direction

This function selects bi-directional printing or uni-directional printing. Printing is normally bi-directional, but uni-directional printing allows for precise vertical printing alignment.

Print direction command

When disabled (ON), the preset printing direction overrides the print direction commands sent by your software.

CR centering at top of form

This function is used to improve the paper feed precision when inserting paper, ejecting paper, printing at the top or bottom edge of a paper, and printing near the perforation of a fanfold paper. CR centering refers to the operation of moving the carriage near the center of the paper. When enabled (OFF), the printer performs CR centering at the positions indicated above.

CR wiping at top/bottom

When enabled (OFF), the carriage moves to prevent a paper jam when the printer inserts or ejects a curled paper.

2-pass printing at top/bottom

This function performs 2-pass printing when printing within 1/6 inch of a perforation or 1/6 inch of the top or bottom edge of a paper. When enabled (OFF), the printer performs 2-pass printing to prevent a paper jam when printing at the positions indicated above.

Strobe timing

Selecting Normal (ON) allows the printer to receive data from the computer when the parallel interface’s strobe signal falls. Selecting Special (OFF) allows data receipt when the strobe signal rises.

ACK timing

Specifies the relation between the ACK (acknowledge) timing and the BUSY timing. When set to Normal, the BUSY signal is activated while ACK is being output. When set to Special, the BUSY signal is activated after ACK is output.
