Page 4-21CHAPTER 4 — PROGRAMMABLE FUNCTION STRINGS
LOWQUAL
This PFS is sent to the printer when the System has selected a low quality
or draft print mode using the SCS Page Presentation Media command with
the pq parameter set to 03h. This is normally applicable only for dot matrix
printers. The user can use this PFS to control any mode of operation of the
printer. Start that mode of operation by selecting draft print mode at the
System.
MEDQUAL
This PFS is sent to the printer when the System has selected a medium
quality print mode using the SCS Page Presentation Media command with
the pq parameter set to 01h. This is normally applicable only for dot matrix
printers. The user can use this PFS to control any mode of operation of the
printer. Start that mode of operation by selecting the appropriate print
mode at the System.
HIQUAL
This PFS is sent to the printer when the System has selected a high quality
or near letter quality print mode using the SCS Page Presentation Media
command with the pq parameter set to 02h. This is normally applicable
only for dot matrix printers. The user can use this PFS to control any mode
of operation of the printer. Start that mode of operation by selecting the
appropriate print mode at the System.
SIMPLEX
Print in simplex (single-sided) mode (selected by sending the SCS Page
Presentation Media command with the dx parameter set to 01h). If the
System is printing in duplex mode, it will insert an additional Form Feed
into the data stream if necessary at the end of print jobs.
Note: This command will not be sent by the OS/400 operating system, due
to IBM restrictions, but some application software may support it.
