Print Node Integration for Frappe Framework


#42

@EnSeal just search for “Print Node Settings” in the search bar, you will find one screen link this

In your print node account, setup a new api Key, under API section, like this

Install Print Node in your computer and share the printers, save the settings, everytime, the you need to update the printers.

You just need to configure the actions, how as showed previously in this post

InsecurePlatformWarning


#45

@EnSeal according the link present in the message from you console I’m able to find this

InsecurePlatformWarning
This happens on Python 2 platforms that have an outdated ssl module. These older ssl modules can cause some insecure requests to succeed where they should fail and secure requests to fail where they should succeed. Follow the pyOpenSSL guide to resolve this warning.

Certificate verification in Python 2
Older versions of Python 2 are built with an ssl module that lacks SNI support and can lag behind security updates. For these reasons it’s recommended to use pyOpenSSL.

If you install urllib3 with the secure extra, all required packages for certificate verification on Python 2 will be installed:

pip install urllib3[secure]
If you want to install the packages manually, you will need pyOpenSSL, cryptography, idna, and certifi.


#46

Thank you… Very much. Will try fix the issue


#47

@max_morais_dmm First thanks for your great work.Can this print node print a web page like erpnext pos receipt from inbuilt printer of hand held POS device with andriod OS.The device is Telpo TPS 900.Thanks


#48

@Fred1 first:

I think that print node, wont enable printing in mobile devices, due has no kind of client for that platform

Second, if you are making use of Offline POS, you can use printnode for printer in a printer conected with your computer.


#49

@max_morais_dmm Can you make it possible.I believe many other will need it.


#50

@Fred1 yes it is doable, but it is not on my todo list!


#51

@max_morais_dmm

Trust you are doing very well.

#52

@EnSeal, I used the Zebra Basic Designer, that I downloaded from there https://www.zebra.com/br/pt/products/software/barcode-printers/zebralink/zebra-designer.html

I just got the file, from this editor, edited on Notepad ++, and Upload my template into the Print Format
Into Action, of Print Node Integration I checked the option “Raw Text” and I worked fine


#53

Can you please explain better on this phrase " I just got the file, from this editor,…" I have a Zebra printer as well.

#57

@EnSeal, you have something wrong in your template, I dont have a way to know what’s, since the traceback is not enought to evaluate your template.

But the traceback means, that you have somethine really wrong “Junk” on line 16 column 0 of your template


#58

@max_morais_dmm

Thank you for being very helpful. I have been able to make a headway on this.

Face with new Challenge adding table to the receipt design. Any help with a template to play with that includes item description, qty and price.
Tax Subtotal and total…

Will really appreciate any help.


#59

@EnSeal the table on xml escpos are really limited!

I have some workaround for this, but right now, It may take some time, to implement due I need to patch frappe framework.


#60

Hello @max_morais_dmm

Regards


#61

It’s on my todo list, but I didn’t have enought time to work on this.

I didn’t got what you mean by tag priting
