The program is designed to work with most EPOS hardware.
The receipt printer is just selected from the drop down in Utilities | Configuration | Receipts.
The Auto receipt drop down on that page is used to automatically print receipts after each transaction.
The receipt bye line specifies the text to appear at the foot of each receipt.
The logo checkbox will print a logo at the top of the receipt using the receipt.bmp image file in the 4POS folder. Just amend or replace the file to suit.
Finally, the store heading is set from the Utilities menu, Store print heading.
The Utilities | Custom receipt may be used to customize the design for the store.
After each sale a tendered box is displayed with the receipt and invoice print buttons.
Typically receipt printers connect either by USB or Com port (traditional POS). The receipt printer must first have been added as any Windows printer using the driver disc supplied with it.
Note that receipt printers require the exact printer driver for the specific model, do not use alternatives.
It is recommended a test page is printed (Start, Printers, Printer, Properties, Print Test Page).
Utilities | Configuration | Till configuration
A cash drawer is typically daisy chained from a receipt printer (RJ11 type connector) or less frequently connected directly to a serial port (Com port).
For receipt printer connected (daisy chained) drawers:
Utilities, Configuration, Receipts
Select the printer
Utilities, Configuration, Till configuration
Enter the 'Receipt printer connect control sequence'.
The sequence is specific to the receipt printer. The Epson TM T88 is: 27,112,48,55,121
Note that many receipt printers have two RJ11 sockets on the back, one for the cash drawer, the other for a pole display. Ensure the one marked DK is used for the cash drawer.
The open till drawer shortcut on 4POS is the F8 key.
For direct connect drawers, which are connected directly to one of the computers serial (COM) ports the 'Open character' is the character sent to the port (which pulses the solenoid latch and opens it).
Many till units will operate with any character, some require a specific code (a frequent one is 7).
There are more detailed setup notes and codes here.
