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.
