Notes on PDF:

            a. If you aren’t having any issues printing returns

in Sail Tax, you don’t need to change anything and Sail

Tax will print returns using PCL as it always has.  Archived

Returns will be created as PDF files.

            b. Changing to PDF return printing.  If you have

been having issues printing returns or you want to print to a

printer that doesn’t have PCL you can change to PDF return

printing.  In Sail Tax, click on Settings.  You will see a new

option group named “Print Returns Using:” where you can

click on the “PDF Printing” button.

            c. Using PDF return printing.  When completed PDF

forms show on screen, click on the printer icon to print the

tax form(s).  On the print options screen, set the Page

Scaling to “None” or “Actual Size”.  If you can’t see the scan

line at the bottom of the printed ST-1, you will have to set the

Page Scaling to “Shrink to Fit” or “Fit”.

            d. IDOR requires that paper sales tax forms for

submission be printed on a laser printer with non-magnetic

toner.  File copies can be printed to any printer using PDF.

            e. Sail Tax cannot print duplex (2-sided) PDF’s.

Two page ST-1’s are perfectly acceptable to submit to IDOR

(assuming the taxpayer is not required to efile.)

            f. The PCL or PDF setting in Sail Tax is per each

computer.  If you have multiple computers sharing data on

a network, you can have some using PCL and some using

PDF to print returns.


(Version 2.51 fixes installation of PDF components which

was an issue on some computers.)
