TCP/IP printers on additional serial ports

→ Click on to add TCP/IP printers to the list.
A mask with the following settings options will open:

• Activate TCP/IP printer on this interface

  ☑ Maps the interface defined below in a TCP/IP port.

  ☐ Disabled (default)

• Device name: The printer can be connected to one of the following connections, provided that they are available on the device:

  • USB COM1

  • USB COM2

  • Perle COM1

  • Perle COM2

Data are forwarded bidirectionally at serial interfaces. This means that other serial devices such as barcode scanners or scales can be operated too.

• Search for devices...: Opens a dialog allowing you to select the device file. 3 device files are available for each device; the Designation column shows the type of device file:

  • (GENERIC) [device designation]: Generic type. The name of the device file ends in a consecutive number which depends on the boot procedure or the order of insertion. Example: /dev/ttyUSB0

  • (BY PORT) [device designation]: According to USB port. The device file is in the /dev/usbserial/ directory. The name of the device file ends in the number of the USB port that the device is plugged into. Example: /dev/usbserial/ttyUSB_P12

  • (BY USBID) [device designation]: According to USB ID. The device file is in the /dev/usbserial/ directory. The name of the device file ends as follows: _V[Vendor ID]_P[Product ID]. Example: /dev/usbserial/ttyUSB_V067b_P2303

• TCP/IP port number: Port on which the interface is to be mapped (default: 9100).

• Poll criterion: Criterion according to which the interfaces are mapped.

  • Always: Maps constantly without polling.

  • DSR (M1): Maps only if the relevant line is set by the serial device.

  • DCD (M5): Maps only if the relevant line is set by the serial device.

• Poll frequency: Amount of time between polls (default: 1 sec)

• Speed: Input and output speed (default 9600 baud).

• Parity: Parity bits that are to be used. Possible values:

  • None

  • Even

  • Odd

• Stop bits: Use up to two stop bits. (default: 1)

• Word width: Sets the number of bits used per byte.

  • 5

  • 6

  • 7

  • 8

• Use RTS/CTS flow control

  ☑ Hardware flow control will be used.

  ☐ Not used (default)

• Use XON/XOFF flow control

  ☑ Software flow control by sending start/stop signs will be used.

  ☐ Not used (default)

• Use DSR flow control

  ☑ Hardware flow control with DSR for output will be used.

  ☐ Not used (default)
