* To implement printing on a platform, the following functions must be

* 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.
