I am using escpos for printing the Token in our Queue managment system python. I need to put the company logo in header of the token. I am trying to do the same as below.
printer.set(align='center')
#printer.qr("You can readme from your smartphone")
printer.image("index/index_statics/img/brand/Webp.net-resizeimage.png")
But the image is always alignef to left. I have seen many links on the same. but nothing that I can understant. I am very new it. Please help to understand the issue and please help me to resolve the same. The printer is ZKTeco (ZKP8008) termal printer
This is not an ESC/POS question. Just that the printer can interpret ESC/POS does not mean that escpos is the good category for a framework/library question.

I create a billing system, which involves scanning QR code and inputting the data into the fields item and quantity as shown in picture. However I'm unable to figure out how to upload the data into the fields. My scanner is able to decode the QR code, but how do I fill in the fields automatically as I scan my code. Is there a way to do this?

I have a pdf where 2 pages have total of 6 attachment boxes where you can click on them and after clicking you can choose the image file and it will be inserted in the pdf, so I want to do this using python I have tried pymupdf and after checking it is showing me it is one of the widgets as button but I don't know exactly how can I use pymupdf to upload the images automatically, I have tried several techniques but it didn't help so I had to remove the attachment boxes. Can anyone please help me out here? I have used this also as I saw in the documentation adding an annot_file or embedded file can do the trick but I am not sure and confused, has anyone ever did it?
After clicking on one of the image icon
I have tried several techniques there were a few methods of attaching files using annotations and update_file for the document object. If this helps to understand the problem more clearly. Thanks
I am new to web development, trying to make a image gallery and I can't figure out how to make the collection page.
Please include what do you want to do, what have you tried in order to do that and hopefully, where or what error message are you receiving.
Only then, me or someone will be able to help you.
If you don't know how to start, you are in the wrong place.
You should start watching some tutorial on youtube, then read some documentation and help yourself with more tutorials.

Hi im new in python programming,
currently im in a project which need to find distance between 2 points (lat&lon) offline.
I know google maps provide this service but i cant use it since it has a limit for free account.
So, im googling around and find pyroutelib2 can do this for me with using openstreetmap map data.
pyroutelib link
and now im kinda stuck. im running on Windows 8 x64. my python is 2.7.
i have downloaded pyroutelib from this link
http://svn.openstreetmap.org/applications/routing/pyroutelib2/
and have my country map (osm.bz2 file) ready. the problem is, while i type the command
loadosm.py f:\asia.osm car
loadosm.py f:\asia.osm.bz2 car
loadosm.py f:\asia.osm.pbf car
(the osm file is in different directory)
in my console, the osm file wont be loaded and returning this message:
Loaded 0 nodes
Loaded 0 cycle routes
Searching for node: found None
anybody please help me. Thanks
I get the same output. Either pyroutelib2 or its documentation is broken.
I suggest to just use another routing library/tool. See the OSM wiki about routing as well as the list of online routers and offline routers. There are lots of interesting solutions available.
Check out osmapi, it's what I've used to get OSM files and import them into pyroutelib2. I don't know if that will solve your problems, but I've had luck going that route.
If I add a feed URL to Google Reader or to a desktop feed aggregator, I receive nice results. The URL is:
http://estaticos03.marca.com/rss/futbol_1adivision.xml
But when I fetch the same URL from a script (python script, using feedparser library) I am getting slightly different content for the same results (the title for each entry, for example, is different and all in uppercase).
I believe something is done on the server-side to try to discourage people like me to parse the content for my own projects (the feed is from a popular football newspaper), but I am not sure about it. I tried to pass some user agents (like the google reader one) but still no luck, so maybe they check the IP as well? I am really confused.
Any idea why is this happening to me?
Thanks!
AFAIK Google Reader does some "magic" in the content to beautify it. They strip some tags and styles to avoid breaking their interface.
Can you provide more details on the differences?
Did you changed the user agent of your script? Try to mimic Firefox and see what happen.
All right folks, I found it. I analyzed the source XML received (as #TryPyPy). I had been trusting too much the feedparser library. Latest official version (4.1) has a bug related to mistakeing the title tag from media namespace instead of the original one:
http://code.google.com/p/feedparser/issues/detail?id=76
So I reinstalled from trunk and now everything is OK. Thanks for helping anyway!
