IN is a one-byte hexadecimal number that specifies the page length in inches. IN ispresent only if parameter LL equals 0. Valid values for IN are X'01' to X'71'. If IN isgreater than the maximum value, the maximum value is used. If both LL and IN arezero, the control is ignored.Set Horizontal Tabs (ESC D)1B 44 TT .. TT 00This control sets the horizontal tab stops. The maximum number of tab stopssupported is 28. The sequence terminates with the NUL control code. If the nullterminator is missing, the printer treats the next 28 bytes as tab stops and ignoresall the data bytes following the 28 bytes until a Null is received. If the printerreceives this control code with no tabs, all horizontal tab stops are cleared.TT is the list of tab stops as character positions relative to the left edge of thephysical page. Valid values are X'01' to X'FF'. Tab stops must be specified inascending order. Entries not in ascending order are ignored.Begin Emphasized Print (ESC E)1B 45This control starts emphasized print mode (bold style). Emphasized printingcontinues until the printer receives an End Emphasized Print (ESC F) control or theprinter is initialized.End Emphasized Print (ESC F)1B 46This control ends emphasized print mode (bold style).Begin Double-Strike Print (ESC G)1B 47This control starts double-strike printing (all text characters are double struck).Double-strike printing continues until the printer receives an End Double-Strike Printcontrol (ESC H) or the printer is initialized.End Double-Strike Print (ESC H)1B 48This control ends double-strike printing.Change Font (ESC I)1B 49 NNThis control selects the font to be used for printing.NN is the one-byte local font identifier number that specifies the font. The mappingof the local font identifier is dependent upon the printer’s emulation mode setting. InAppendix D. Personal Printer Data Stream (PPDS) 201
