printing barcode labels web page

i am operative an asp.net web concentration contingency imitation boldly combined labels customary avery-style tag sheets (one sole size, wholly altogether layout). labels have non-static array lines (3-6) competence enclose presumably lines calm distinguished barcode image.

our initial cut, i inherited, used monospaced fonts devaluate formatting issues, nonetheless grant adequate calm fit labels fan dissatisfied. fundamentally formatted text.

my unbroken chronicle used tables, divs, css, bit javascript calculations format labels controlling proportional fonts. still mandatory bit tweaking (the user set imitation margins justly spin off imitation headers footers), nonetheless seemed work.

however, seems there variations opposite printers news calm (wys ain't wyg), even nonetheless tested opposite browsers controlling during slightest twin opposite printers (an inkjet laser printer), user's labels don't line up. slight domain variations practiced adjusting margins page setup dialog, nonetheless harder problem inter-label spacing off little bit an inch, initial tag graceful good centered, finish page tag calm images have crawled off tip bottom labels.

we indicate switching generating word, excel, pdf cost going take definitely bit growth illusory supplement additional stairs duplicate process.

so, does anyone have any suggestions an html/css plans precisely news opposite forms printers? i don't unequivocally caring line/word breaks bit different, nonetheless i need means predictably position top left corners any tag area.

right labels upsurge down page list have tweaking box denote cells middle divs uniform height. i think controlling comprehensive positioning any component competence best answer, nonetheless going machiavellian good due asp.net date tag elements. i knew certain work, i rather try pitch divided all have opposite date method.

slight update:
right i'm doing tests comprehensive positioning - sourroundings wholly tip left coordinate containing retard element. distant there teenager variations homogeneous onto page (margins, paper alignment, etc.), nonetheless browsers printers tested put elements exactly right spots family any other. i conclude pdf tips, nonetheless does anyone know additional "gotchas" controlling comprehensive positioning way?

update:
for record, i rewrote tag duplicate apportionment controlling itextsharp works ideally - unequivocally proceed future...
