## Receipt Printers
#### USB

If you want to use a network printer or a usb printer (in windows), use the net use command, eg: (from the command prompt)
net use lpt1 \\computerName\printerName /persistent:yes
(You can find out what your printerName is by going to windows explorer and typing in \\computerName The printer will (hopefully) come up in the list of network-available items.
Then in LibrePOS configuration, choose file and type in lpt1.

#### Parallel

To test if your printer is well connected, issue the following commands. Change lpt1 or lp0 to whichever port you are using
Under Windows:
Under Linux
Try configuring the printer as "file" and type in lpt1 (or /dev/lp0 for linux).

#### Serial

Check your cable. Some serial printers require a null modem cable, a standard serial cable+null modem adapter or even some other configuration in order to work, please check your manual or contact the manufacturer. Bytes2000 has confirmed in the forums that a Standard DB9 Null modem adapter from Radio Shack that implements the "Loop back handshaking" pin configuration
To test if your printer is well connected, issue the following commands. Change com1 or ttyS0 to whichever port you are using
Under Windows:
Under Linux
If the printer prints the word "test" then you are ready to go. On LibrePOS the easiest way to use the printer is with RXTX as it is bundled with LibrePOS.
Non Epson printers may have problems with the image command as the ESC/POS standard varies a bit from different manufacturers. In particular, some CBM printers can't handle the image command. If this happens, try removing the image from the ticket.

## Cash drawer

Ensure your printer can control your cash drawer. The drawer is controlled by the printer.

## Barcode scanner

Bar code scanners come in many flavors from wands to handhelds to flat beds. Scanners also have a variety of ways to attach to your PC terminal: USB, Serial, PS/2, BUS, Bluetooth.
The easiest to get working are the PS/2 model handhelds. They require NO software or configuration (typically). They plug into a keyboard port and 'key in' the UPC barcode (and usually a carraige return). The PS/2 barcode scanners work EXCELLENT with LibrePOS in the stores I have setup. This is NOT just for adding inventory, but works to key in orders...Just like any other store does.
You can pickup used barcode scanners for $5 to $50. These are adequate for reading UPC barcodes. While laser scanners support data matrix, 2D, PDF417 and other formats...why spend the money for this? If you are only working retail, you will typically be using just plain vanilla UPC barcodes. Save your money for a decent receipt printer.
The CueCat USB Port scanner works with zero configuration on Linux Fedora Core 6. The usbhid driver auto-detects and magically converts the data to numbers. Simply click in the barcode field in LibrePOS and run the scanner over a barcode. The cord is a good 6 feet long too. And, of course, the price is right when buying used.
