Function Documentation

◆ hl_pl_enter()

void hl_pl_enter	(	struct hl_drv *	t,
		enum hl_prn_lang	lang
	)

◆ hl_pl_reset_to_pjl()

void hl_pl_reset_to_pjl ( struct hl_drv * t )

◆ hl_pjl_mode_printer_start()

void hl_pjl_mode_printer_start ( struct hl_drv * t )

◆ hl_pjl_mode_printer_stop()

void hl_pjl_mode_printer_stop ( struct hl_drv * t )

◆ hl_pjl_media_management()

static void hl_pjl_media_management	(	FILE *	prn,
		const struct hl_job_options *	j
	)

static

Handle the medium's type, format and orientation

Parameters

[in]	prn	Where to send the PJL command to
[in]	j	Printer and Job specific options

Based on the MEDIATYPE option the printer adapts its temperature of the fixing unit for a useful print result

Based on the PAPER option the printer adapts the OPC drum width the laser reaches. Or in other words: it defines the startposition of the leftmost dot (3 mm away from the left medium's edge).

Todo:: What about INTRAY*SIZE instead of PAPER ?

I guess, the ORIENTATION option is useful only for smaller media than letter or A4 to inform the printer about the real geometry to print to. Think about a DIN C6 envelope: printing on it makes a real difference if its inserted in landscape or portrait.

Todo:

What about the media source? SOURCETRAY (AUTO, MPTRAY, TRAY1 …)

What about the manual feed medium size? MPTRAYSIZE

◆ hl_pjl_duplex_management()

static void hl_pjl_duplex_management	(	FILE *	prn,
		const struct hl_job_options *	j
	)

static

Handle the medium's simplex versus duplex print

Parameters

[in]	prn	Where to send the PJL command to
[in]	j	Printer and Job specific options

The simplex/duplex mode should be set explicitly, because at the printer a default can be set. And the default might not be the print mode the user expects for his/her print job.

Precondition: This command makes sense only for printers which are capable to print in duplex.

◆ hl_pjl_mode_job_start()

void hl_pjl_mode_job_start	(	struct hl_drv *	t,
		struct hl_job_options *	j
	)

◆ hl_pjl_mode_job_end()

void hl_pjl_mode_job_end ( struct hl_drv * t )
