- class escpos.printer.Usb(idVendor, idProduct, usb_args=None, timeout=0, in_ep=130, out_ep=1, *args, **kwargs)[source]¶
Bases:
escpos.escpos.Escpos
USB printer
This class describes a printer that natively speaks USB.
inheritance:
- class escpos.printer.Serial(devfile='/dev/ttyS0', baudrate=9600, bytesize=8, timeout=1, parity='N', stopbits=1, xonxoff=False, dsrdtr=True, *args, **kwargs)[source]¶
Bases:
escpos.escpos.Escpos
Serial printer
This class describes a printer that is connected by serial interface.
inheritance:
- class escpos.printer.Network(host, port=9100, timeout=60, *args, **kwargs)[source]¶
Bases:
escpos.escpos.Escpos
Network printer
This class is used to attach to a networked printer. You can also use this in order to attach to a printer that is forwarded with
socat
.If you have a local printer on parallel port
/dev/usb/lp0
then you could startsocat
with:socat -u TCP4-LISTEN:4242,reuseaddr,fork OPEN:/dev/usb/lp0
Then you should be able to attach to port
4242
with this class. Otherwise the normal usecase would be to have a printer with ethernet interface. This type of printer should work the same with this class. For the address of the printer check its manuals.inheritance:
- class escpos.printer.File(devfile='/dev/usb/lp0', auto_flush=True, *args, **kwargs)[source]¶
Bases:
escpos.escpos.Escpos
Generic file printer
This class is used for parallel port printer or other printers that are directly attached to the filesystem. Note that you should stay away from using USB-to-Parallel-Adapter since they are unreliable and produce arbitrary errors.
inheritance:
- class escpos.printer.Dummy(*args, **kwargs)[source]¶
Bases:
escpos.escpos.Escpos
Dummy printer
This class is used for saving commands to a variable, for use in situations where there is no need to send commands to an actual printer. This includes generating print jobs for later use, or testing output.
