English to Dutch Tech/Engineering IT (Information Technology) patent application/printing system

A block first initializes a left/right (L/R) counter variable to its default value of right because it is assumed that the first page of the book will be one the right side.

If the user has not specified that the page should be forced, a block flip-flops the L/R counter such that if it was set to right it is changed to left and if it was set to left, it is changed to right and the program returns to the block to retrieve the next "should print" page in the record.

In addition, a variable text box counter is incremented representing the number of variable text boxes appearing on each page.

Ik denk dat "counter" wel door "teller" kan worden vertaald, maar hoe zou ik "teller" in combinatie met (1) "left/right" en (2) "variable text box" mooi kunnen vertalen?

Alvast bedankt voor jullie suggesties!
