Will these work with epson tm-c3500 printer?

It appears that the Epson TM-C3500 can take a roll with a maximum outer diameter of 4" and a core size of 1.75" - 2.25". The RL3998XW has a 6" outer diameter and a 3" core. We do carry 2" core roll products but the outer diameters are at 5".

will these work withe Primrea LX500? it is the only one not listed. Thank you

The RL3998GW has a 3" core and is intended for Primera models LX900, LX910, LX1000, and LX2000. If you're using the smaller LX500 model, you'll want to choose a 2" core roll like the RL3997GW listed at the link below. https://www.onlinelabels.com/products/rl3997gw

Are rolls available without the perf? We're concerned they won't apply properly with our automatic labeler.

Our standard inkjet roll products have perforations between each label, however you can request a custom configuration by contacting our Customer Support Team. We can be reached at 888-575-2235 or by submitting a support ticket at the link below. https://www.onlinelabels.com/Support/SupportRequest.aspx
