Print codes are only used if the method for printing MSDS sheets is on-line printing. Use the MSDS Print Code F/M program to maintain the MSDS print codes. Print codes are used during on-line printing to print sheets that are stored on the disk and were either typed or scanned into third-party software such as an imaging package or a word processor, e.g., WordPerfect. Print codes are established with a default directory path where the MSDS sheets are stored. Print commands (see the section on the MSDS Print Command F/M Program) are then assigned to each print code by warehouse to instruct the system how to print the MSDS sheets through the third-party software. These print codes are then assigned to MSDS IDs in the MSDS ID F/M to direct the system on print instructions for the MSDS sheets, summary sheets and cover letters (if used). These instructions are used by the MSDS On-line Print and On-demand Print Programs.
