When you define a receipt printer in Horizon, you choose whether to use Windows or direct port printing. If you use Windows printing, you may need to configure your printer in Windows. (For instructions, see your Windows user’s guide.) If you use port printing, you can further refine your printer output by using commands called “escape sequences.” Escape sequences let you set and reset printing options. You can use prefix and suffix escape sequences.
You use the prefix escape sequence to change printer settings before the printing of a slip or receipt. With prefix escape sequences, you can do one or more of these things:
• | Set the printer to retract the paper before it begins printing. |
• | Change the default printer font for printing slips. |
• | Change the form length and width for printing slips. (This is useful when the printer is not a dedicated slip printer.) |
You use the suffix escape sequence to reset the printer after the printing of a slip or receipt. With suffix escape sequences, you can do one or more of these things:
• | Set the printer to advance the paper to a suitable “tear off” point after printing. |
• | Change back to the default printer font after printing slips or receipts. |
• | Change back to the default form length and width after printing slips or receipts. |
For example, by using escape sequences, the printer can advance the paper after it finishes printing to a point where the slip or receipt can be torn off easily. When the next receipt or slip is printed, the printer can retract the paper to the appropriate position to begin printing. (For more information about the escape sequences for your specific printer, refer to your printer’s documentation.)
