Printing apparatus and inclination correction method |
February 5, 2008 |
| When bidirectional multi-pass printing is carried out by use of a printing head having an inclination, even if a bidirectional printing is somewhat displaced, an inclination of a printing position is corrected in a state where "band unevenness" is suppressed as much as possible. In order |
