python-escpos - Python library to manipulate ESC/POS Printers

Description

Documentation Status

Python ESC/POS is a library which lets the user have access to all those printers handled by ESC/POS commands, as defined by Epson, from a Python application.

The library tries to implement the functions provided by the ESC/POS-command-set and supports sending text, images, barcodes and qr-codes to the printer.

Text can be aligned/justified and fonts can be changed by size, type and weight.

Also, this module handles some hardware functionalities like cutting paper, control characters, printer reset and similar functions.

Since supported commands differ from printer to printer the software tries to automatically apply the right settings for the printer that you set. These settings are handled by escpos-printer-db which is also used in escpos-php.

Dependencies

This library makes use of:

Documentation and Usage

The basic usage is:

fromescpos.printerimportUsb""" Seiko Epson Corp. Receipt Printer (EPSON TM-T88III) """p=Usb(0x04b8, 0x0202, 0, profile="TM-T88III")
p.text("Hello World\n")
p.image("logo.gif")
p.barcode('4006381333931', 'EAN13', 64, 2, '', '')
p.cut()

Another example based on the Network printer class:

fromescpos.printerimportNetworkkitchen=Network("192.168.1.100", profile="TM-T88III") #Printer IP Addresskitchen.text("Hello World\n")
kitchen.barcode('4006381333931', 'EAN13', 64, 2, '', '')
kitchen.cut()

Another example based on the Serial printer class:

fromescpos.printerimportSerial""" 9600 Baud, 8N1, Flow Control Enabled """p=Serial(
devfile='/dev/tty.usbserial',
baudrate=9600,
bytesize=8,
parity='N',
stopbits=1,
timeout=1.00,
dsrdtr=True,
profile="TM-T88III"
)
p.text("Hello World\n")
p.qr("You can readme from your smartphone")
p.cut()

Note

It is highly recommended to include a matching profile to inform python-escpos about the printer's capabilities.

The full project-documentation is available on Read the Docs.

python-escpos - Python library to manipulate ESC/POS Printers

Description

Documentation Status

Python ESC/POS is a library which lets the user have access to all those printers handled by ESC/POS commands, as defined by Epson, from a Python application.

The library tries to implement the functions provided by the ESC/POS-command-set and supports sending text, images, barcodes and qr-codes to the printer.

Text can be aligned/justified and fonts can be changed by size, type and weight.

Also, this module handles some hardware functionalities like cutting paper, control characters, printer reset and similar functions.

Since supported commands differ from printer to printer the software tries to automatically apply the right settings for the printer that you set. These settings are handled by escpos-printer-db which is also used in escpos-php.

Dependencies

This library makes use of:

Documentation and Usage

The basic usage is:

fromescpos.printerimportUsb""" Seiko Epson Corp. Receipt Printer (EPSON TM-T88III) """p=Usb(0x04b8, 0x0202, 0, profile="TM-T88III")
p.text("Hello World\n")
p.image("logo.gif")
p.barcode('4006381333931', 'EAN13', 64, 2, '', '')
p.cut()

Another example based on the Network printer class:

fromescpos.printerimportNetworkkitchen=Network("192.168.1.100", profile="TM-T88III") #Printer IP Addresskitchen.text("Hello World\n")
kitchen.barcode('4006381333931', 'EAN13', 64, 2, '', '')
kitchen.cut()

Another example based on the Serial printer class:

fromescpos.printerimportSerial""" 9600 Baud, 8N1, Flow Control Enabled """p=Serial(
devfile='/dev/tty.usbserial',
baudrate=9600,
bytesize=8,
parity='N',
stopbits=1,
timeout=1.00,
dsrdtr=True,
profile="TM-T88III"
)
p.text("Hello World\n")
p.qr("You can readme from your smartphone")
p.cut()

Note

It is highly recommended to include a matching profile to inform python-escpos about the printer's capabilities.

The full project-documentation is available on Read the Docs.
