HP ML5590/91 manual SI Select Pitch 12 cpi, Default = 20 cpi, Size, Default = Single

SI Select Pitch 12 cpi, Default = 20 cpi

IBM emulation only. Sets the pitch to be engaged when the printer control panel is set for 12 cpi and the SI command is received.

Size, Default = Single

Change to Double for double width and height printing.

Skip Over Perforation, Default = No

Change to Yes if you want the printer to go to the next page when it comes within 1" (25 mm) of the bottom of the page. Keep it set to No if your software has its own page formatting controls.

Style, Default = Normal

Change to Italics if you want the printed characters to be slanted.

Time Out Print, Default = Valid

If your software spends a long time processing between portions of data it feeds to the printer, change the setting to Invalid to keep your printer from dumping the received data while it is waiting for more.

Wait Time, Default = 1 sec.

Sets the amount of time the printer will wait for more data before moving to the form tear-off position.

Zero Character, Default = Unslashed

If you want the printer to use a slash to distinguish the number zero from the capital letter O, change the setting to Slashed.
