2 * P-Touch PT-2450DX printer driver
3 *
4 * P. Pemberton, 2009
5 *
6 * Specs:
7 * Printer head is 128 dots, 180dpi, for a total print area of ~18mm vertical
8 * by however long your TZ label tape is.
9 * Printhead size is (128/180)=0.711[.] inches, or 18.0622[.] mm
10 * Each dot is (18.062/128) = 0.1411[.] mm
11 * Printable area is (numdots * 0.1411) mm
12 *
13 * Tape width Margins Printable area
14 * mm dots mm dots mm dots
15 * 6mm 42 1.0mm 7 4mm 28
16 * 9mm 63 1.0mm 7 7mm 49
17 * 12mm 85 2.0mm 14 8mm 57
18 * 18mm 127 3.0mm 21 12mm 85
19 * 24mm 170 3.0mm 128 18mm 128 ***
20 *
21 * 24mm is slightly odd. Because the printhead is only 128 dots (18mm), the
22 * margins are enforced by this, and not the driver software. It is impossible
23 * to print right to the edge of a 24mm label in a PT-2450DX.
