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.
