Lexmark MX722 PRESCRIBE Emulation P43.4 Technical Reference - Page 14

Lexmark Confidential until announced PRESCRIBE commands 14 The odd‑numbered parameters (A1, A3, A5, and A7) specify a whole‑inch value. The even‑numbered parameters (A2, A4, A6, and A8) specify a fraction in 100ths of an inch. Page Length and Page Width settings that are larger than the default margin limits are ignored. The factory defaults are set to be longer and wider than the largest possible size; thus, default bottom and right margins are used. The margins are always positioned with respect to the default edge limits. C1: Page orientation This parameter designates the logical page position with respect to the physical page. C1 value 0 1 Description Portrait orientation Landscape orientation C3: Default font The C3 parameter sets the default font. C3 can be set to one of three modes: C3 value 0 1-79 255 Font selection Font 1 for PCL emulation. Font 8 for ProPrinter and LinePrinter emulations. Sets the default font to the specified font number. Sets the default font to the front panel default or the PJL setting. L1-L8: Edge limits The L parameters are used to vary the size of the logical page and to position it with respect to the physical paper. The L parameters are always acknowledged in ProPrinter and LinePrinter emulations. Parameters L1-L4 are always acknowledged in PCL emulation. Parameters L5-L8 are used in PCL emulation only if the FRPO parameter R3 is set to 1. The default edge limits are as follows (all pel dimensions are 300 dpi): Edge limit PCL (R3=0) PCL (R3=1) or PrPrinter Top 1/6", 4 mm, 50 pels 1/5", 5 mm, 60 pels Left 1/4", 6 mm, 71 pels 1/5", 5 mm, 60 pels Bottom 1/6", 4 mm, 50 pels 1/5", 5 mm, 60 pels Right 1/4", 6 mm, 71 pels 1/5", 5 mm, 60 pels The top‑ and left‑edge limits determine the position of the logical page. The bottom‑ and right‑edge limits determine the size of the logical page. L1-L4 FRPO parameters are always interpreted with respect to the top and left edges of the physical page. L5-L8 FRPO parameters are always interpreted with respect to a lettersize sheet of paper, with default top‑ and left‑edge limits (0.20"). For example, to set edge limits of approximately 2 mm (24 pels @ 300 dpi) on all four sides of any‑size paper, the following FRPO commands are used: FRPO L1, 0; FRPO L2, 8; FRPO L3, 0; FRPO L4, 8; FRPO L5, 10; FRPO L6, 72;cmnt 11" - .2" - 10.72" = .08" = 24 pels; FRPO L7, 8; FRPO L8, 22;cmnt 8.5"- .2" - 8.22" = .08" = 24 pels;
