How to print screen

Set the LCD screen as you desired then use the command below to start printing.

•

“PRINALL” on page  405

Use the command below to abort your printing.

•

“COPA” on page  282

The following items can be set for the printing.

Settings for the above items are stored in the non-volatile memory (SRAM), thus they do 
not revert to the initial settings by executing “PRES” command on page 404. Use the 
command below to restore the initial settings.
