can only concatenate str (not "bytes") to str while using the print function

[aleperuz]

When i try to print a photo with pret the program crush with error.
can only concatenate str (not "bytes") to str
i modified the program to make sure that the given variable is a string.
self.send(c.UEL + str(data) + c.UEL)
If I print simple text it prints without errors. So I understood that with pret you can only print text, even if I don't understand why since there is the variable that converts pdf and images into files that the printer understands.
Hope this problem is solved.

Hey @aleperuz,

I tried the same, although i am getting the following.

Fixed the line as below.

How had you fixed this?

@deFr0ggy yes use python 2 and add the fixes from another issue

Try this one:

edit the script that will send commands in the language of your printer (pjl.py, pcl.py or postscript.py)
Add this:
import sys
reload(sys)
sys.setdefaultencoding('iso-8859-1')
