Report Print hints

Follow this to get correct print margins, print area and position on paper

Example : for A4 size paper

 

Printed Page Size : A4 ( 210x297 mm )

Left Margin : 25 mm

Right Margin : 10 mm

Top Margin : 10 mm

Bottom Margin : 10 mm

 

QTF Print Calculations are done @ 600DPI  1 mm = 600/25.4 = 6000 / 254 is 23.6 dots per mm

Values in Report setting are int. multiplication by 6000 then divide by 254 we get better precision

 

Report Setting :

These calculated margins can be used for printing to PDF file

Left Margin : 25 * 6000 / 254 = 590

Right Margin : 10 * 6000 / 254 = 236

 

Top Margin : 10 * 6000 / 254 = 236

Bottom Margin : 10 * 6000 / 254 = 236

 

Report Print area ( Report.SetPageSize ( cx, cy ) )  Portrait orientation

cx = (PageWidth - LeftMargin - RightMArgin (mm)) * 6000 / 254

  = ( 210 - 25 - 10 ) * 6000 / 254 = 4133

cy = (PageHeight - TopMargin - BottomMargin (mm)) * 6000 / 254

  = ( 297 - 10 -10 ) * 6000 / 254   = 6543

For Landscape orientation use Report.SetPageSize ( cy, cx )

Margin Calculation when printing to Printer  

This is My observation with some of the PCL Printers. May be different with your printer.

Checked with Ricoh, Minolta, Samsung laser printers.

 

Value 4 may be different for different printers.

 

Report Margins ( Report.Margins ( TopMargin, LeftMargin )

 

TopMargin = ( Top margin - 4 ) * 6000 / 254

        = ( 10 - 4 ) * 6000 / 254 = 142

LeftMargin = ( Left Margin - 4 ) * 6000 / 254

        = ( 25 - 4 ) * 6000 / 254 = 496

 

With these settings you will get Correct margins and print area on the paper.

 

Getting Print area in the center of the printed page.

Use the same calculation as above to get your Print Area.

Do not set Margins. Page margins to be 'NULL'

Your document will be printed on center of the page
