For preserving the least toxic and most culturally relevant Tumblr heritage posts.

Image descriptions and plain text captions of written content are expected of all screenshots. Here are some image text extractors (I looked these up quick and will gladly take FOSS recommendations):

-web

-iOS

-android

Please begin copied raw text posts (lacking a screenshot that makes it apparent it is from Tumblr) with:

I made the icon using multiple creative commons svg resources, the banner is this.

Unprintable characters perhaps?

I've seen it do this when the DIP switches on a serial printer are set to a baud rate of 115200 but the PC is sending at 9200bps. Especially when sending graphics, like a logo, but also just when connected and not even receiving a print job.

You've got to edit the printer port in windows to force 115200 baud rate.

Heaps of these receipt printers still use a serial COM port.

Thanks for the perspective! I never had a chance to play with one of them.
