I don't know if it's due to the printer, but what happens is that I often tear tracks when pulling the transfer paper.
I still get better results than what I was getting with photoresist, but that probably just means that I'm not very good at etching PCBs.
Its tearing that happens when you use the iron.
I use the yellow paper (cheap from aliexpress now),
print on the shiny side
I usually get round to organizing a bunch of boards on A4 size
For each board leave enough space on 2 sides.
I don't cut the paper to the exact size of the pcb, but longer on 2 sides.
The extra, form a tab that i fold over the board, then sticky tape it.
Now iron it.
Hot iron, i think is about 210degC
Firm and only needs a few passes.
I use an old ancient iron, mum probably used it in the 50ties, lol. Its heavy all by itself.
I still stick it in a bath of water after, more out of habit, but maybe helps, at that stage rather not guess just continue with what i did before, its not that much more trouble.
I've used HP printer in past, now use Brother HL-L2375DW very successfully.
Except I fire up the old laptop with WinXP to print it.
The linux driver just doesn't quite work, not sure about it.
still, its never worked as well as photoresist (positive). but i seem unable to get good
positive photoresist these days.
its also very troublesome to do those transparency prints.
