| 19 * To implement printing on a platform, the following functions must be | |
| 20 * defined: | |
| 21 * | |
| 22 * int mch_print_init(prt_settings_T *psettings, char_u *jobname, int forceit) | |
| 23 * Called once. Code should display printer dialogue (if appropriate) and | |
| 24 * determine printer font and margin settings. Reset has_color if the printer | |
| 25 * doesn't support colors at all. | |
| 26 * Returns FAIL to abort. | |
| 27 * | |
| 28 * int mch_print_begin(prt_settings_T *settings) | |
| 29 * Called to start the print job. | |
| 30 * Return FALSE to abort. | |
| 31 * | |
| 32 * int mch_print_begin_page(char_u *msg) | |
| 33 * Called at the start of each page. | |
| 34 * "msg" indicates the progress of the print job, can be NULL. | |
| 35 * Return FALSE to abort. | |
| 36 * | |
| 37 * int mch_print_end_page() | |
| 38 * Called at the end of each page. | |
| 39 * Return FALSE to abort. | |
| 40 * | |
| 41 * int mch_print_blank_page() | |
| 42 * Called to generate a blank page for collated, duplex, multiple copy | |
| 43 * document. Return FALSE to abort. | |
| 44 * | |
| 45 * void mch_print_end(prt_settings_T *psettings) | |
| 46 * Called at normal end of print job. | |
| 47 * | |
| 48 * void mch_print_cleanup() | |
| 49 * Called if print job ends normally or is abandoned. Free any memory, close | |
| 50 * devices and handles. Also called when mch_print_begin() fails, but not | |
| 51 * when mch_print_init() fails. | |
| 52 * | |
| 53 * void mch_print_set_font(int Bold, int Italic, int Underline); | |
| 54 * Called whenever the font style changes. | |
| 55 * | |
| 843 | 56 * void mch_print_set_bg(long_u bgcol); |
| 442 | 57 * Called to set the background color for the following text. Parameter is an |
| 58 * RGB value. | |
| 59 * | |
| 843 | 60 * void mch_print_set_fg(long_u fgcol); |
| 442 | 61 * Called to set the foreground color for the following text. Parameter is an |
| 62 * RGB value. | |
| 63 * | |
| 64 * mch_print_start_line(int margin, int page_line) | |
| 65 * Sets the current position at the start of line "page_line". | |
| 66 * If margin is TRUE start in the left margin (for header and line number). | |
| 67 * | |
| 68 * int mch_print_text_out(char_u *p, int len); | |
| 69 * Output one character of text p[len] at the current position. | |
| 70 * Return TRUE if there is no room for another character in the same line. | |
| 71 * | |
| 72 * Note that the generic code has no idea of margins. The machine code should | |
| 73 * simply make the page look smaller! The header and the line numbers are | |
| 74 * printed in the margin. | |
