Continuous paper for printing labels on labelprinter using Word mailmerge

very important so i can finish my project soon.
I use Word Automation with my VB6 Appl.
I still need to find how i can adjust continuous printing or continuous paper when using Mailmerge to print labels.
I can find other labelpapersize than A4 in the Word Label details window but only Letter Mini B4 and some other but not continuous or customesize paper.

Alternatively I can allso set up the correct pageheight every time depending on the amount of labels i want to print.
This works, i can change pageheight manually before printing through page setup and this i can change after the mailmerge (but is limited i think up to 55cm).
A4 setting is selected now in labelssettings for labelpaperheight.
So probably i will have somehow to set to continuous paper anyway, or give my calculated correct paperheight with a custom size setting somehow depending on the amount of printed Labels.
I really need some help here.
I am using a tichetprinter now for testen this. In the printer driver setting i can choose allso papersize Receipt length (58mm x 3276mm). So with this printer i can print up to 3 meters labels. A real labelpriter will probably have more better settings. But for testing this will do for now.
Only the Word labeldetails papersize doesn't seem to have sutch papersetting for receipt or continuous or custum size paper, or am i overlooking something?? For now i can only print upto 6 labels , with 7 labels i exead the A4 papier height.
PLease some help.
