| * To implement printing on a platform, the following functions must be |
| * defined: |
| * |
| * int mch_print_init(prt_settings_T *psettings, char_u *jobname, int forceit) |
| * Called once. Code should display printer dialogue (if appropriate) and |
| * determine printer font and margin settings. Reset has_color if the printer |
| * doesn't support colors at all. |
| * Returns FAIL to abort. |
| * |
| * int mch_print_begin(prt_settings_T *settings) |
| * Called to start the print job. |
| * Return FALSE to abort. |
| * |
| * int mch_print_begin_page(char_u *msg) |
| * Called at the start of each page. |
| * "msg" indicates the progress of the print job, can be NULL. |
| * Return FALSE to abort. |
| * |
| * int mch_print_end_page() |
| * Called at the end of each page. |
| * Return FALSE to abort. |
| * |
| * int mch_print_blank_page() |
| * Called to generate a blank page for collated, duplex, multiple copy |
| * document. Return FALSE to abort. |
| * |
| * void mch_print_end(prt_settings_T *psettings) |
| * Called at normal end of print job. |
| * |
| * void mch_print_cleanup() |
| * Called if print job ends normally or is abandoned. Free any memory, close |
| * devices and handles. Also called when mch_print_begin() fails, but not |
| * when mch_print_init() fails. |
| * |
| * void mch_print_set_font(int Bold, int Italic, int Underline); |
| * Called whenever the font style changes. |
| * |
| * void mch_print_set_bg(long_u bgcol); |
| * Called to set the background color for the following text. Parameter is an |
| * RGB value. |
| * |
| * void mch_print_set_fg(long_u fgcol); |
| * Called to set the foreground color for the following text. Parameter is an |
| * RGB value. |
| * |
| * mch_print_start_line(int margin, int page_line) |
| * Sets the current position at the start of line "page_line". |
| * If margin is TRUE start in the left margin (for header and line number). |
| * |
| * int mch_print_text_out(char_u *p, int len); |
| * Output one character of text p[len] at the current position. |
| * Return TRUE if there is no room for another character in the same line. |
| * |
| * Note that the generic code has no idea of margins. The machine code should |
| * simply make the page look smaller! The header and the line numbers are |
| * printed in the margin. |
