HP 1200 HP PCL/PJL reference - PCL 5 Comparison Guide - Page 97

The second example given here initializes a PCL 5 print job for printing Japanese text. The major differences from the previous example are that it specifies A4 paper, initializes the text parsing method to Shift-JIS, selects Win3.1J as the primary symbol set, selects MS-Mincho as the primary font. ?%-12345X@PJL @PJL SET RESOLUTION=600 @PJL PAGEPROTECT=OFF @PJL RET=MEDIUM @PJL ENTER LANGUAGE=PCL ?E?&l1x1h26a0o8c6e60F?&a5L?&t31P?(19K ~?(s1p10v0s0b28752T The last line (2 lines, as shown) in the above example is a PCL 5 initialization string. This set of commands resets the printer, specifies 1 copy, specifies the paper tray as a paper source, chooses A4-size paper, selects portrait orientation, VMI=8 (6LPI), sets top margin to 6 lines, selects a text length of 60 lines, a 5-column left margin, Shift-JIS parsing, WIN3.1J symbol set, and a proportional, 10-point, upright, text-weight MS-Mincho font. After the PCL print data, the following commands would be used to complete the job: ?E?%-12345X Font Metric Calculation Accurate character placement relies on the ability to predict character width and height. As a character's point size changes, so does its width and height. (CAP displacement, the distance the CAP moves for vertically rotated text, is a full-width calculation.) In proportionally spaced fonts, character widths also vary from character to character within the font. Variable character widths add complexity to maintaining accurate line widths, page breaks, or WYSIWYG operation. To support most proportionally spaced fonts, font metrics must be extracted from the font metric files. ENWW Printer-Specific Differences 2-49
