18 /* | |
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. | |
