Quik Reports for DOS only has one place to control the page length of a report, and that is the 'Layout' function under the Print/Export menu. This layout is report-specific, and when you go to this screen, you enter the number of lines for the report, which in your case is 72.

Any other changes for printer setup (character size, etc) would have to be done through the System Manager printer maintenance.

In QR Print/Export menu there is an option "Layout" where you can set the lines per page. For continuous labels (depending on what version/release of QR you are using) you must set this to be "0" or "99". 99 for older versions (prior to 6.5A, I believe) and 0 for 65A.

The reason you are getting a blank page is because you have the lpp set to 72, so QR then performs a form feed before printing the next page of information.
