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 *
56 * void mch_print_set_bg(long_u bgcol);
57 * Called to set the background color for the following text. Parameter is an
58 * RGB value.
59 *
60 * void mch_print_set_fg(long_u fgcol);
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.
