+ * 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.
