kandi X-RAY | python-escpos Summary

python-escpos is a Python library. python-escpos has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Python library to manipulate ESC/POS Printers. 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 standard usage is send raw text to the printer, but in also helps the user to enhance the experience with those printers by facilitating the bar code printing in many different standards, as well as manipulating images so they can be printed as brand logo or any other usage images migh have. Text can be aligned/justified and fonts can be changed by size, type and weight. Also, this module handles some hardware functionalities like, cut paper, carrier return, printer reset and others concerned to the carriage alignment. The following example shows how to initialize the Epson TM-TI88IV * NOTE: Always finish the sequence with Epson.cut() otherwise you will endup with weird chars being printed.

            Access printer connected at Virtual Printer Port (USB001) using python-escpos on Windows 10
            Asked 2022-Jan-11 at 10:00

            I have created a printing module, which work with printer connected at serial port using printer.Serial("COM5") interface provided by python-escpos.

            But now, I have to switch to USB printer rather than serial. My USB printer is connected at virtual printer port (USB001). Now, printer.USB() requires vendorID and productID but in my case when I see Device Instance Path, it does't contain vendorID and productID (screenshot is attached below). I am stuck here that how can I connect with this USB printer.

            Please note that my printer is R290 thermal printer and I have downloaded its driver from http://itambition.com/printer.html. The printer is connected at USB001 and test page is being printed successfully.

            I have resolved the issue using following steps:

            • connect USB printer
            • install R290 driver from http://itambition.com/printer.html. it will setup USB001 for usb printer
            • from printer & scanners menu, select printer properties and share the printer
            • open cmd as administrator and run:

            net use lpt1 \your-systems-hostname\printer-sharename

            • now connect printer.File("LPT1") interface of python-escpos and start printing

            Answered 2020-Jul-12 at 01:15

            Isn't it a problem with the printer's USB mode setting?
            TM-T20II printer has the modes of USB vender-defined class (COM Port) and USB printer class.
            The VID/PID is USB vender-defined class=0x04b8:0x0202 and USB printer class=0x04b8:0x0e15 respectively.

            TM-T20II Technical Reference Guide page 89

            You should be able to change it with the printer's setting utility.
            Alternatively, try changing the PID designation to 0x0202 as is, or try communicating as a COM port instead of a raw USB device.

            Or it is possible that the advanced printer driver or Windows print spooler is already using the device and other programs cannot be used.
            If the device driver is installed, try uninstalling it.

            I want to read back ASB and other status results in python-escpos. I thought the ._read() method would work but I get a "AttributeError: 'Serial' object has no attribute '_read'" error. I have verified the _read() method is there with inspect.

            python3 python-escpos: product id / PID for EPSON TM-M30 needed
            Asked 2020-Mar-04 at 13:06

            Since some years I am running and maintaining an online P.O.S. system, where peripheral hardware and print system is managed by a RasPi with pure debian & python3.

            My costumer bought a new receipt printer, which is an EPSON TM-M30. Currently he's using a TM-T88IV for that.

            The python-escpos printer code snippet currently is

            ...

            ANSWER

            Answered 2020-Feb-29 at 02:30

            The interface board of the EPSON printer is modularized and commonly used by many printers.
            Interface Board
            UB-U

            The PID is for that interface board and is the same for any printer that uses it.

            For example, for Japanese materials, the PID is the same for TM-m30 and TM-T88VI.
            TM-m30 page 86
            TM-T88VI page 118

            Therefore, VID 0x04B8 and PID 0x0202 can be considered as IDs of USB interface boards of EPSON printers.

            If you can get the Manufacturer and Product String Descriptors written in the document, you will be able to determine the printer model.
