Ask HN: What format is this?
{D1531,1000,1501|} {C|} {U2;0130|} {D1531,1000,1501|} {AX;+000,+000,+00|} {AY;+05,0|} {PC000;0922,0555,15,15,H,11,B|} {RC00;<FE/>LABELTITLE</FE>|} {PC001;0865,0555,15,15,H,11,B|} {RC01;<FE/>VOLTAGE</FE>|} {PC002;0796,0040,
That looks like commands sent to a Century Eagle label printer. It appears to say:
{D1531,1000,1501|} Set label pitch to 153.1mm, width 100.0mm, height 150.1mm.
{C|} Clear the image buffer
{U2;0130|} Reverse feed by 13.0mm
{D1531,1000,1501|} Set label pitch to 153.1mm, width 100.0mm, height 150.1mm.
{AX;+000,+000,+00|} Adjust label position and so on...
I'm assuming that this was interpreted by something that changed { to ESC, | to LF and } to NIL.
