Printing PCB in strict 1:1 scale is not a easy job. Though you could specify 1:1 print scale in Protel, the output may still real 1:1. And even you got a 1:1 output on one printer, you may not get a 1:1 print on aother printer.
The way I did is make a two round print. Following are the steps: 1) Draw 2 lines on a bland PCB file, one on X , one on Y direction. Suppose both of their length are 2 inches. 2) Print the PCB with 1:1 scale in Protel print option. 3)Measure the length of lines on the paper output. 4) If the line length of output is not 2 inches, calculate the adjustment ratio, and enter it into Protel's X scale and Y scale. 5) You could re-do step 2 to 4 to verify it is trule 1:1 on both X, Y direction. 6) Print the final true 1:1 PCB output.
