Hi, i'm using arduino UNO connected to a thermal printer (QR701) and using the adafruit thermal printer library, the printer works perfectly but it keeps printing 8 before starting to print. This keeps happening even if i try to change the code or the connected library. The only occasion when it doesn't happen is where i print the test page of the printer.

I find the search tool on the forum su... is difficult for me to find even my own topics.
Read the titles of the recent topics. The posting was very close in time. Go for the "Project guidance" section.
@sararararara - @Railroader suggested looking at this topic (three days/600 posts ago)... he suggested how the user could find their mistake. From where did you copy your code? You probably also copied the same problem/error. For you to get printing, look at your code for printer.feed(8);... which should be telling the printer to print "8" line feeds... (edit - I see "feed" is a printer function)
@Railroader - "Latest" ... 3 days (600 posts) ago... found it. But, this forum should be searchable without getting scroll-wheel cramps.
I know, not mastering that searching yet. Usually posts are flagged when that similar.
600 posts in 3 days... How many topics/new auestions? Worse then I imagined anyway.
Hahaha..ahaha. Sorry... I just now understand that the two topics are the same user. Some days I am more -blind- incompetent than other days.
