Yeah, inches. I was wondering why the message I posted yesterday drew no responses, I guess you missed the units. In my test print from a few-days-old CVS gimp-print there's a move printer head down 90.87 inches command: 00000055 1b ( v 04 00 8e ff 00 00 I'm following a strict interpretation of the docs which specifies this as an unsigned 32 bit little endian integer number of dots, which, at 720 DPI, translates to 90.87 inches. If you interpret this as a signed 16 bit little endian number followed by 16 bits of trailing garbage, it makes slightly more sense, except that the docs specify that the printer head should never be moved in the negative Y direction. Negative relative positions are only allowed for horizontal motion. Any thoughts? Eric |
