Cumberland lists it as laser printer compatible and names a heat resistant glassine window, which is what stops a plastic window patch distorting under fuser heat. The two heavier C4 window mailers in the same range, MPN 612344 and MPN 612347, carry no printer rating at all, so a run of addressed envelopes belongs on this code and not on those.\u003c\/p\u003e\u003cp\u003eIt is 90gsm rather than the 100gsm of the two heavy duty booklet mailers, which is the trade off for feeding cleanly through a printer path. The secretive lining still conceals the contents, and the window still lets a barcoded or addressed enclosure show through when the address is printed on the document instead. Both routes work on this code, which is unusual in the range and the reason it is worth the price step.\u003c\/p\u003e\u003cp\u003eThe rest of our \u003ca href=\"\/collections\/mailing-envelopes\"\u003emailing envelopes\u003c\/a\u003e, the wider \u003ca href=\"\/collections\/cumberland\"\u003eCumberland range\u003c\/a\u003e and our \u003ca href=\"\/collections\/mail-labelling-packaging\"\u003email and packaging supplies\u003c\/a\u003e carry the other C4 formats and the adjacent sizes.\u003c\/p\u003e","brand":"Cumberland","offers":[{"title":"Default Title","offer_id":50552471126272,"sku":"CU6123412","price":63.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0863\/5419\/8784\/files\/Cumberland_Envelope_C4_Laser_BookletMailer_Window_6123412_hero_Mega_Office_Supplies.jpg?v=1791399833","url":"https:\/\/megaschoolsupplies.com.au\/products\/laser-envelope-c4-booklet-mailer-strip-seal-window-face-secretive-white-box-250","provider":"Mega School Supplies","version":"1.0","type":"link"}
