It depends on factors that nobody would know, except yourself. The quality of the inkjet printer, the quality of the ink, the quality of the paper, etc. Is this a newer printer, and do you have the driver set for higher dot-per-inch setting? Are you using a refilled cartridge? Are you using paper made specifically for inkjet?
When you print the barcodes, are they nice and sharp, or do they bleed a little? Does it smear when you rub it? Does it bleed if you get the page wet?
If in doubt, it's not that expensive to go print it out on a laser printer. In our city, the local library has printing service, as do many of the office supply stores and copy stores. Average is about 10 Canadian cents per page.
Overseas, we have Internet bars, photo centres, office centres, and such. They normally print on A4 paper, but most can do 8.5 x 11 paper on request.
