WordPerfect® 5.1 for DOS

Problem

Symptoms: A customer is unable to print 3.5" x 1" labels on the Toshiba P321 printer with the Toshiba P321 driver. When the customer is printing with a 0" top margin, the leading between line one and line two is less than the leading between line two and line three and subsequent lines on the page. Solutions: This is caused by a PTSIZE/4 expression in Printhead Bias Top under Printer Commands for this printer. How/Why: WordPerfect automatically makes a vertical adjustment at the top of the document in order to accommodate for the white space above a descender to the top of the page. This adjustment is approximately 1/4 of the PTSize. In order for the customer to be able to print at the 0" position, a PTSIZE/4 is entered in Printhead Bias Top to move the text up that much, thus eliminating the effects of WP's adjustment. The limitation is that WP accounts for all of the vertical space on the page. Any amount of space adjusted for in Printhead Bias Top is looked at basically the same as a text adjustment up, and if a margin is set less than that, WP will not make a vertical movement until the amount of vertical space in the Printhead Bias is accommodated for. In other words, if you have a Printhead Bias of 1", then you set a margin for 0" all text on the page that is contained between 0" and 1" will print on top of itself in the same vertical position. In this customer's situation, the following workaround solved the problem: 1. Enter the PTR Program, retrieve the .PRS file, and press Enter on the desired printer 2. Move to Printer Commands and press Enter 3. Move to Printhead Bias Top, and press Right Arrow to move to the expression box 4. Remove the PTSIZE/4 statement, exit and save the .PRS file It is important to note that after this change is made, the customer will not be able to print right at the top of the paper because of the adjustment that WP makes.
