My inkjet is about to run out of ink and I'm thinking of buying a laser printer to print the transparencies. 

General process: 

2 prints of PCB cut aligned and glued to each other > Pr-Sensitised PCB exposure > development and etching. 

In general with the Inkjet I print several times on the same sheet and any offcut can then be attached to a paper A4 sheet for printing later on, minimal waste.

My concern in buying a laser is the heat and the possible warping of the transparency especially running it through several times. 

Am I better of sticking with the inkjet due to the warping of the transparency that the laser can/could cause?

I included a pic to show that all these three PCBs were done in multiple print runs with one A4 transparency sheet on an inkjet. I don't know but I don't think I can do the same with a Laser printer.

Thanks all, but it seems lasers are to finicky. Right laser, sourcing and using the right transparency, then in future if I try to use the transfer method on non pre-sensitised boards it has to be the right toner for transfer. 

One mistake or fault and cost of repair could be a nightmare. For the cost of repair/parts of a laser I can buy a dozen cheap new multifunction ink-jets that will last me 5+ years.

I may stick with the ink-jets, 100% success rate so far. 

It just occurred to me that with a laser and using the transfer method (translucent paper 'crowie') I could just use the laser to create a silk screen then iron it on the PCB. I may see if I can buy a cheap second hand laser. It would be nice to have a cct board with a silk screen of sorts.
