Con®guration Item	Description	Value Options
Font Usage	Font usage allows you to select the amount of memory	Low, Medium, or High
	that the printer control unit (computer) will use for font
	management. Select the font usage according to the type
	of print jobs you run.
	Select Low font usage for jobs using a normal number of
	fonts with normal point sizes, but not double-byte fonts.
	Medium font usage indicates an abnormal single-byte
	character set (SBCS) printing mode; select it for jobs
	using a large number of fonts or very large point sizes,
	but not double-byte fonts. High font usage is primarily
	for double-byte font jobs.
Page Segment Usage	This is used to allocate space for IPDS source for page	Low, Medium, or High
	segments and overlays. Set to Low if the size or number
	of page segments and overlays is a small. Set to High if
	the size or number of page segments and overlays is
	large.
Overlay Usage	This parameter is used to allocate space for a cache of	Low, Medium, or High
	ready-to-print overlays. Set to Low if a few small
	overlays are used. Set to High if many or large overlays
	are used.
Overlay Cache	This parameter is used to activate or deactivate overlay	Yes or No
	caching. Set to No if overlays are not reused multiple
	times or if overlays are not reused in the same location
	on subsequent pages.
Input Buffer Size	This parameter is used to allocate space for the IPDS data	Low, Medium, or High
	that was just received from the server before being
	processed by the control unit. Set to Low if pages contain
	little data or if printing from PSF/MVS on a System/370
	channel or an ESCON channel (this is because of the
	frequent IPDS acknowledgment rate). Set to High if
	printing pages with large amounts of data (such as large
	images).
Output Buffer Size	This parameter is used to allocate space for ready-to-print	Low, Medium, or High
	pages, including pages between the transfer points of a
	continuous-forms, duplex printer. Set the value to Low if
	these conditions are met:
	v The pages contain little data
	v This is a simplex printer
	v This is a duplex printer with a distance between
	transfer points of less than 400 inches.
	Set the value to High if these conditions are met:
	v The pages contain large amounts of data, especially
	shaded areas
	v This is a duplex printer with a distance between
	transfer points of over 400 inches.
Direct Attach	This entry shows if printing is to occur in direct-printing	Yes or No
	mode when connected to an MVS or OS/390 operating
	system, with no host-assisted recovery procedures such
	as retransmission of pages after a forms jam.
	The host system programmer will inform you whether
	this entry should be set to Yes.
